Cross-examination of Prof. Herbert MacDonell (part 2)

Witness: Prof. Herbert MacDonell
Examiner: Marcia Clark
Called by: Defense • Date: Tuesday, August 1, 1995 • Utterances: 251
Marcia Clark cross-examined defense blood spatter expert Prof. Herbert MacDonell on two fronts: his expert fees (attempting to establish bias) and the scientific limitations of his sock testimony. Clark methodically forced MacDonell to concede he performed no specific experiments to test his conclusions about the 'little balls' on the inner surface of OJ's sock, and that he could not rule out alternative explanations — including that they were caused by the pheno test itself or by contact with Nicole Brown's blood during the murder.
1 (The following proceedings were held in open court:)
2 MS. CLARK:

May I have a moment, your Honor?

3 (Discussion held off the record between the Deputy District Attorneys.)
4 MS. CLARK:

All right. Mr. MacDonell, you indicated, did you not, that you have been paid 10,500 for your work thus far?

5 PROF. MACDONELL:

That is correct.

6 MS. CLARK:

And how much are you paid per day to testify?

7 PROF. MACDONELL:

Ordinarily if I am out of the laboratory for a day overnight I charge $3,000, but in a case of this type where I have traveled so many times and been away from the laboratory so many hours, I cannot charge a rate like that. I really don't know how much time I will charge for. I do not charge on a hourly rate when I've spent this much time. I will charge a fair rate for the amount of time and effort I have put into case.

8 MS. CLARK:

All right. You, as of April 2nd, 1995, had been paid $10,500; is that correct?

9 PROF. MACDONELL:

That includes some travel expenses and my associate and other things. That is not just a basic profit so to speak.

10 MS. CLARK:

And that was up to the point of your examination of April 2nd, 1995, that you had been paid 10,500; is that correct, sir?

11 PROF. MACDONELL:

I believe so, yes.

12 MS. CLARK:

And since that time have you submitted any further bills?

13 PROF. MACDONELL:

No. I haven't had time.

14 MS. CLARK:

And you have done further work, though, nevertheless, have you not?

15 PROF. MACDONELL:

Yes, I have.

16 MS. CLARK:

You have done several day's worth of work, would that be fair to state?

17 PROF. MACDONELL:

Yes, and I have been here three times I think since then.

18 MS. CLARK:

And you have been here for the purpose of your testimony how many days now?

19 PROF. MACDONELL:

I would say maybe ten days, eight or ten days, very close to that. I can look it up. I was here from the 7th to the 12th, the 16th to the 20th, the 25th to the 28th and I'm here again, so that would be--

20 MS. CLARK:

I'm sorry, sir. 7th to the 12th of July?

21 PROF. MACDONELL:

Excuse me. That is--that was another meeting. That was in Philadelphia. I came the 16th to the 20th. That would be five days, and the 25th to the 28th, four days, and I've been here two days, so that would be eleven days.

22 MS. CLARK:

All right. And ordinarily in the average case you charge 3000 a day?

23 PROF. MACDONELL:

That is correct.

24 MS. CLARK:

So if you were to charge--

25 PROF. MACDONELL:

That is to stay overnight. That would be two days.

26 MS. CLARK:

All right. And in this case you have eleven days down, correct?

27 PROF. MACDONELL:

That's correct.

28 MS. CLARK:

So if this were your average case, you would have charged 33--this is terrible. This is terrible. Roughly $18,000 for your work thus far if it had been the average case, correct?

29 PROF. MACDONELL:

No.

30 MR. NEUFELD:

Objection.

31 PROF. MACDONELL:

It would have been several--

32 THE COURT:

Wait, wait, wait. Mr. Fairtlough, keep your voice down. If I can hear you, it is way too loud.

33 MR. FAIRTLOUGH:

Yes, your Honor.

34 THE COURT:

Sustained. Rephrase the question.

35 MS. CLARK:

If you were charging your average fee in the average case at $3,000 per day after eleven days being present, how much would that be?

36 MR. NEUFELD:

Objection.

37 THE COURT:

Sustained. He said he is not going to bill on his normal schedule.

38 MS. CLARK:

How do you intend to bill, sir?

39 PROF. MACDONELL:

I'm not really sure. I must confess I have never had a case that has been of this type. I will be fair and not do anything that will cost more money. I've saved the Defense considerable money by using golden opportunities, air flights booked at $300.00 a trip instead of the first two were $1409 a ticket. I think I've saved them $3300 on that alone. I'm not trying to make a profit, just a reasonable wage.

40 MS. CLARK:

Your Honor, there would be an objection, motion to strike as nonresponsive.

41 THE COURT:

Overruled.

42 MS. CLARK:

Mr. MacDonell, I'm attempting to ask you now what you intend to bill the Defense. Can you answer that question, sir?

43 PROF. MACDONELL:

Not at this point.

44 MS. CLARK:

Do you intend to bill them at fifty percent of your normal rate?

45 MR. NEUFELD:

Objection. Asked and answered, your Honor.

46 THE COURT:

Overruled.

47 PROF. MACDONELL:

I really don't know. I have never had a case like his. I will be fair and charge them what I think the amount of time I put in would have been had I been in my laboratory. I do not charge a rate everyday because I don't spend eight hours a day.

48 MS. CLARK:

Mr. MacDonell are you attempting to convey to this jury that you are not in this for the money?

49 THE COURT:

Sustained.

50 MR. NEUFELD:

Objection, your Honor.

51 THE COURT:

Sustained.

52 MS. CLARK:

You do intend to make a profit on your work in this case, do you not?

53 PROF. MACDONELL:

I hope so yes.

54 MS. CLARK:

Since you have spent at least eleven days since April 2nd of 1995, you do intend to make more money than the 10,500 you have already been paid; isn't that correct?

55 PROF. MACDONELL:

I really don't know until I have sat down and assessed the time I have spent. I would say that is an approximation that might be accurate, but I do not wish to limit my bill by stating in court what I'm going to charge. I have done that before and that is all the attorney would pay me because under oath I said I'm going to charge $400.00 more and it turned out to be 550 or something and they wouldn't pay me the extra 150, so that is why I say I will be fair, but I don't want to commit myself to something and then find out I have to live with it and feel I didn't get a fair price.

56 MS. CLARK:

All right. Do you feel that you will bill at least 10,000 more for the services you have rendered?

57 MR. NEUFELD:

Objection, asked and answered. He said he--

58 THE COURT:

Overruled.

59 PROF. MACDONELL:

As far as the amount of expenses go on top of what I have done, I would say that is approximately close.

60 MS. CLARK:

To the minimum that you will bill?

61 PROF. MACDONELL:

It might exceed it. I don't know.

62 THE COURT:

All right. Let's move on.

63 MS. CLARK:

Sir, you indicated that you are a New York state crime lab board member?

64 PROF. MACDONELL:

I was.

65 MS. CLARK:

For the advisory committee?

66 PROF. MACDONELL:

I was, yes.

67 MS. CLARK:

Isn't it true, sir, that you last attended a meeting of that advisory committee in 1982?

68 PROF. MACDONELL:

That is probably right. They quit sending me the notices of the meeting and so I couldn't go.

69 MS. CLARK:

And you were not involved in quality control; isn't that correct?

70 PROF. MACDONELL:

That's correct.

71 MS. CLARK:

Now, at this point, sir, with the one photograph of the one ball that you have shown us, at this point all we have is your memory and your testimony to rely upon for the appearance of all the other little balls, the six or seven that you have seen; is that correct?

72 MR. NEUFELD:

Objection, argumentative and asked and answered this subject six times.

73 THE COURT:

Sustained.

74 MS. CLARK:

May we approach, your Honor?

75 THE COURT:

Proceed.

76 MS. CLARK:

No, not on the question. May we approach?

77 THE COURT:

Yes.

78 (The following proceedings were held at the bench:)
79 MS. CLARK:

Counsel's repeated speaking objections which have been very loud and very vociferous have gone unchecked by the Court thus far, although the Court has warned counsel.

80 THE COURT:

I warned him in front of the jury. This is a pretty severe sanction, I think.

81 MS. CLARK:

And the People are asking that counsel be admonished to refrain from these speaking objections. I think it is very unfair. I think it is deliberately disruptive. It has required us to step back and regroup a number of times and that is why the "Asked and answered" objections are particularly unfair when we are being precluded from getting the answer because of counsel's repeated speaking objections which are lengthy and loud.

82 THE COURT:

All right. Your request is considered. I have already admonished Mr. Neufeld to--regarding his objections.

83 MR. NEUFELD:

Your Honor, guidance on one thing because she is raising an issue in point. Am I not allowed to say, "Objection, hearsay" or "Objection, asked and answered"? Am I only allowed to say "Objection"?

84 THE COURT:

You are allowed to state the legal grounds.

85 MR. NEUFELD:

Is "Asked and answered" a legal ground? That is all I'm asking. I won't do it again.

86 THE COURT:

It is in the common parlance here, although it is not technically asked.

87 MS. CLARK:

It is "Asked and answered six times now" and "How many times do we have to go over this?"

88 THE COURT:

I know. I've already admonished him once in front of the jury, Miss Clark. That is a pretty severe sanction.

89 MR. NEUFELD:

Okay.

90 MS. CLARK:

It is one the People have suffered a number of times.

91 THE COURT:

Yes, it is.

92 (The following proceedings were held in open court:)
93 THE COURT:

All right. Thank you, counsel. Proceed.

94 MS. CLARK:

At this point, in view of the fact that we have no photograph of the six or seven other little balls, we have only your testimony to rely on; is that correct, sir?

95 MR. NEUFELD:

Objection, argumentative, asked and answered.

96 THE COURT:

Overruled. Sustained.

97 MS. CLARK:

I didn't get an answer last time.

98 THE COURT:

I have sustained the objection, counsel.

99 MS. CLARK:

Sir, is it your testimony that we rely on right now with respect to the appearance of how those other little balls looked, your verbal description?

100 MR. NEUFELD:

Objection, asked and answered.

101 THE COURT:

Overruled. That is a different question. You can answer the question.

102 PROF. MACDONELL:

Apparently so.

103 MS. CLARK:

And sir, you cannot say when those little balls got onto the--that inner surface before your examination on April 2nd, 1995; isn't that true?

104 MR. NEUFELD:

Objection, asked and answered yesterday.

105 THE COURT:

Overruled.

106 PROF. MACDONELL:

That's true.

107 MS. CLARK:

And you cannot say that the compression stain that occurred on the outer surface of the sock was made at the same time that the little balls got onto the inner surface on the other opposite inner side?

108 PROF. MACDONELL:

I can put a limit on it, yes.

109 MS. CLARK:

But you cannot say that they occurred at the same time, can you, sir?

110 PROF. MACDONELL:

No, they couldn't have occurred at the same time. One had to precede the other. If--maybe by just a second or a fraction of a second, but the inside did not occur--on surface 3 did not occur before 1 and 2.

111 MS. CLARK:

And you cannot say exactly when it occurred after the outer compression stain was made; isn't that correct, sir?

112 PROF. MACDONELL:

That's correct.

113 MS. CLARK:

And you cannot even tell this jury that those little balls on the inner surface are associated with the outer compression stain; isn't that correct?

114 PROF. MACDONELL:

I conclude that they were.

115 MS. CLARK:

But you cannot tell this jury that they were absolutely associated with the same outer stain; isn't that correct?

116 PROF. MACDONELL:

That is correct.

117 MS. CLARK:

Now, sir, just with respect to the outer compression stain or swipe, either one that you say it now can be, you cannot exclude the possibility, can you, that the stain was made during the commission of the murder at Bundy; isn't that correct?

118 MR. NEUFELD:

Objection. Asked and answered yesterday.

119 THE COURT:

Sustained. That question was asked yesterday.

120 MS. CLARK:

Sir, you cannot exclude the possibility then that that outer compression or swipe stain was made by making contact with the step covered with the blood of Nicole Brown; isn't that correct?

121 MR. NEUFELD:

Objection, asked and answered.

122 THE COURT:

Overruled.

123 PROF. MACDONELL:

That is correct.

124 MS. CLARK:

You cannot exclude the possibility that that outer compression or swipe stain on the sock was made at the time of the murder as the murderer stepped near the neck of Nicole Brown; isn't that correct?

125 PROF. MACDONELL:

Well, the neck--it is possible, yes, but I would sooner think your example yesterday of a thumb or something that sticks out would be more likely. The neck would be too wide an area of blood staining to limit the transfer to that size stain. I mean it might be possible, but I would agree more with a thumb or something that sticks out.

126 MS. CLARK:

Then you would agree, sir, that it would be more probable that it would be the thumb or bloody hand of Nicole Brown that could have come in contact with the sock to create that compression stain; is that correct?

127 THE COURT:

Sustained. Sustained. Speculation, counsel.

128 MS. CLARK:

You cannot exclude that possibility can you, sir?

129 MR. NEUFELD:

Objection. Asked and answered yesterday, and argumentative.

130 THE COURT:

Overruled. Sustained.

131 PROF. MACDONELL:

I cannot exclude.

132 MR. NEUFELD:

I'm sorry.

133 THE COURT:

Sustain the objection. It is speculation. Proceed.

134 MS. CLARK:

Sir, can you exclude the possibility that the stain on the outer--that the outer stain that you call a compression or a swipe could have been made by brushing up against the bloody hand of Nicole Brown?

135 MR. NEUFELD:

Speculative and asked and answered.

136 THE COURT:

That was asked yesterday. Sustained.

137 MS. CLARK:

All right. Sir, you were not present--we showed photographs yesterday of the pheno tests done with that swab in this picture. Do you recall that?

138 PROF. MACDONELL:

Yes.

139 MS. CLARK:

And we discussed the performance of that pheno test that uses distilled water to perform the test, correct?

140 PROF. MACDONELL:

You can use distilled water, yes.

141 MS. CLARK:

It was apparent to you, from looking at the photograph of the sampling step that was being shown in that photograph, that that was the method that was being used in that--with the sock, correct?

142 MR. NEUFELD:

Your Honor--

143 PROF. MACDONELL:

Correct.

144 MR. NEUFELD:

Objection, asked and answered.

145 THE COURT:

Overruled.

146 PROF. MACDONELL:

That's correct.

147 MS. CLARK:

All right. Now, that test you were not present when it was conducted; isn't that correct?

148 PROF. MACDONELL:

That's correct.

149 MS. CLARK:

You do not know how much pressure was applied by the person swabbing the sock with that Q-tip, correct?

150 PROF. MACDONELL:

That's correct.

151 MS. CLARK:

You do not know how much water was used in swabbing the sock with that q-tip, correct?

152 PROF. MACDONELL:

I don't know how much they used. I know how much they should have use.

153 MS. CLARK:

Okay. But you don't know how much they did use, do you?

154 PROF. MACDONELL:

That's correct.

155 MS. CLARK:

You don't know how large an area was swabbed, do you?

156 PROF. MACDONELL:

No, I don't.

157 MS. CLARK:

And if the blood was difficult to see and this test was being conducted under normal lighting in an effort to do a blood search with that swab, it could have been a very large area, could it not, sir?

158 MR. NEUFELD:

Objection, speculation.

159 THE COURT:

Sustained.

160 MS. CLARK:

Nevertheless, you do not know how large an area it was?

161 THE COURT:

Excuse me, counsel. If I hear the bases and I hear urgings for objections and if I can hear it, the jury can hear it. Proceed.

162 MS. CLARK:

Since you were not present then, sir, you cannot tell us what large--how large an area was swabbed with that swab, correct?

163 PROF. MACDONELL:

I can state that it did not go to the edge of the stain itself, because the blood is very clear, crisp and sharp at the edge of the stain. Gad a swab that was wetted, gone into that area, it would have diluted and diffused it and it would not look as it does, so it would be confined more to the center than the periphery. That is the only limit I can put on it.

164 MS. CLARK:

With that limitation, sir--but you cannot tell us what portion of the stain contributed the little balls on surface 3, whether it was the periphery or the center of the stain, can you?

165 PROF. MACDONELL:

Yes. I can eliminate the periphery because it did not soak through the fabric, only the center area soaked through, so that is the only area that could have caused the staining on the third side.

166 MS. CLARK:

And that is the only area where the pheno test was conducted, in your opinion, sir?

167 PROF. MACDONELL:

That's where they should have conducted it, where it is the most concentrated, yeah.

168 MS. CLARK:

Well, didn't you just testify, sir, that based on your observation of the periphery of the stain that the way it appeared there was not water swabbed around that periphery that you saw?

169 MR. NEUFELD:

Objection as to the term "Water swabbed."

170 THE COURT:

Sustained. Misstates the evidence is what the correct objection is, counsel.

171 MR. NEUFELD:

Thank you, your Honor.

172 MS. CLARK:

Sir, we discussed the performance of that pheno test using distilled water, correct?

173 PROF. MACDONELL:

Yes.

174 MS. CLARK:

And in the sampling process you would use a wet q-tip to swab the area to see if there was something that appeared to be worth testing, correct?

175 PROF. MACDONELL:

Yes.

176 MS. CLARK:

And you were not present when that test was performed, we've already established that, correct?

177 PROF. MACDONELL:

Correct.

178 MS. CLARK:

So in the--in the swabbing process with a wet q-tip using an amount of pressure you are not aware of, it is your opinion, based on what you saw, that the periphery was not sampled in that manner, that the center of the scene was sampled in that manner, correct?

179 MR. NEUFELD:

Objection as to the form of that question.

180 THE COURT:

Overruled.

181 PROF. MACDONELL:

Yes, that's correct, if it was very wet, the q-tip.

182 MS. CLARK:

And it is your opinion, sir, that the little balls on surface 3 came from that center part of the stain where you opine the swabbing was done?

183 PROF. MACDONELL:

It was done through the cut-out, which is basically the center.

184 MS. CLARK:

Which is where you opine the swabbing was done?

185 PROF. MACDONELL:

That's correct.

186 MS. CLARK:

Did you test the little balls in any manner to determine whether or not if they were blood they were diluted in some manner?

187 MR. NEUFELD:

Objection, asked and answered yesterday.

188 THE COURT:

Sustained.

189 MS. CLARK:

No, I didn't ask about dilution.

190 THE COURT:

That's correct. Reask the question.

191 MS. CLARK:

Did you test the little balls in some fashion to determine whether if they were blood they were diluted?

192 PROF. MACDONELL:

I didn't do any testing. I did an observation and they were deep red and did not appear to be diluted at all.

193 MS. CLARK:

Nevertheless, sir, did you not test; is that correct?

194 PROF. MACDONELL:

I don't know what test you could apply on something that small. I did not; I don't think anyone could.

195 MS. CLARK:

So then you cannot tell this jury that that--whatever it was was not diluted in some fashion, can you, sir?

196 MR. NEUFELD:

Objection. Misstates his testimony.

197 THE COURT:

Overruled.

198 PROF. MACDONELL:

I conclude it wasn't, but I cannot say absolutely one, that it is transferred from the outside and if it were it would be blood, and two, that it is not a concentration in some fashion, but I cannot conceive of how that could occur. It appears to be a fresh sample of a red fluid that is dried and bonded to a fiber.

199 MS. CLARK:

Sir, isn't the basic tenant of science, the cornerstone of it, testing, sir?

KEY QUOTE
200 PROF. MACDONELL:

I think it is observation.

KEY QUOTE
201 MS. CLARK:

And testing, is it not, sir?

202 MR. NEUFELD:

Objection. I think he should be allowed to finish his answer.

203 THE COURT:

Sustained. Let him finish.

204 PROF. MACDONELL:

Observation and then testing. You have to observe something to determine what you might test for. I think it goes in that order.

205 MS. CLARK:

Right, and based upon your observation you form a hypothesis, do you not, or a theory, do you not?

206 PROF. MACDONELL:

I form the conclusion.

207 MS. CLARK:

But then you go to test that conclusion to determine whether it is correct or not; isn't that true, sir?

208 PROF. MACDONELL:

If it is possible to do so you should, yes.

209 MS. CLARK:

And is it not true, sir, that on occasion it will help that you have a theory based on your observation that is disproven by testing? Doesn't that happen, sir.

210 MR. NEUFELD:

Vague. Objection.

211 THE COURT:

Overruled.

212 PROF. MACDONELL:

It could, yes.

213 MS. CLARK:

And in this case, sir, you formed a conclusion based on your observation which you could not test; isn't that correct?

214 PROF. MACDONELL:

That is correct.

215 MS. CLARK:

And so you cannot rule out the possibility that whatever you observed that substance was in those little balls was diluted or not? You cannot rule out the possibility that they were diluted, can you, sir?

216 MR. NEUFELD:

Objection, asked and answered.

217 THE COURT:

Overruled.

218 PROF. MACDONELL:

I can't absolutely rule out anything in any instance and in this case I could not absolutely rule it out as a scientist.

KEY QUOTE
219 MS. CLARK:

Nevertheless, if you had tested those little balls in some fashion you might have been able to; isn't that correct?

220 THE COURT:

Sustained. Sustained.

221 MS. CLARK:

And sir, you cannot rule out the possibility that those little balls were created at the time that the pheno test was conducted on August 4th; isn't that true?

222 PROF. MACDONELL:

Only--it could only be ruled out if the testing was done in the normal procedure, not using a saturated q-tip. That is not what you use when you have a stain of that size. So if it was done properly, there would not be enough liquid to dissolve any blood and transfer it to the inner surface, surface 3, and if it was, it would not appear that red. That is my conclusion.

223 MS. CLARK:

And what test did you do to support that conclusion, sir?

224 PROF. MACDONELL:

There is no test you can do except observation with good optical equipment.

225 MS. CLARK:

Sir, what experiments did you perform on the material of this sock to show that a pheno test using distilled water on a swab would not produce those little balls on the opposite inner side?

226 PROF. MACDONELL:

I didn't have the socks to experiment with. I didn't do that.

227 MS. CLARK:

Did you make any attempt to experiment, as I have suggested, performing a pheno test on a bloodstain to see if that would cause some seepage of microscopic quantities onto the opposite inner side?

228 MR. NEUFELD:

Objection, no foundation.

229 THE COURT:

Overruled.

230 PROF. MACDONELL:

Not on that sock.

231 MS. CLARK:

Did you attempt to do it on any substance or material that was identical to or very similar to that sock?

232 PROF. MACDONELL:

Yes.

233 MS. CLARK:

You did a pheno test and attempted to observe whether there were microscopic particles on the opposite inner side after you performed the test?

234 PROF. MACDONELL:

I didn't do a pheno test or a phenolphthalein test because I knew it was blood. I put it on the material myself.

235 MS. CLARK:

And can you show us the documentation from the pheno test that you conducted with distilled water and a swab on material just like those socks?

236 MR. NEUFELD:

Misstates the evidence.

237 THE COURT:

Sustained. Sustained.

238 MS. CLARK:

Sir, what experiment did you perform on material just like these socks to show that a pheno test on a bloodstain on an outer surface that is just like this bloodstain would leave the microbes or not leave those little balls on the opposite inner side?

239 PROF. MACDONELL:

I applied blood to a similar material, a stocking that was of the lightweight polyester composition, and brushed it on lightly, enough to soak through, and after that I cut out a portion and observed the side opposite corresponding to side 3.

240 MS. CLARK:

Objection. Objection, your Honor. This is not my question. This is nonresponsive.

241 THE COURT:

Sustained.

242 MS. CLARK:

Motion to strike.

243 THE COURT:

The answer is stricken.

244 MS. CLARK:

Mr. MacDonell, please listen to my question. I am asking you now whether you took material just like these socks with blood on it, performed a sampling with a wet q-tip, pressing down with that wet q-tip to sample the blood and then observed the opposite inner side after it had dried to see if there were little balls like those observed on this sock? Did you do that, sir?

245 PROF. MACDONELL:

Not that specific experiment, no.

KEY QUOTE
246 MS. CLARK:

Thank you, sir.

247 (Discussion held off the record between the Deputy District Attorneys.)
248 MS. CLARK:

And lastly, sir, you cannot rule out the possibility that those little balls that you observed are the result of someone with a bloody hand pulling off their socks, can you?

249 MR. NEUFELD:

Objection. Asked and answered yesterday.

250 THE COURT:

Sustained.

251 MS. CLARK:

Did I? I have nothing further.

Prof. Herbert MacDonell
I hope so yes.
MacDonell's blunt admission that he intends to profit from his work, after Clark asked directly whether he was 'in this for the money' — the rare moment of candor Clark was fishing for.
Marcia Clark
Sir, isn't the basic tenant of science, the cornerstone of it, testing, sir?
Clark's central attack: MacDonell drew conclusions from visual observation alone without performing controlled experiments to verify or falsify them.
Prof. Herbert MacDonell
I think it is observation.
MacDonell's revealing answer — he placed observation before testing as the foundation of science, which Clark used to undercut his methodology.
Prof. Herbert MacDonell
Not that specific experiment, no.
The climactic concession of the cross: MacDonell never performed a pheno test on comparable sock material to verify his conclusion that the test could not have caused the inner-surface balls.
Prof. Herbert MacDonell
I can't absolutely rule out anything in any instance and in this case I could not absolutely rule it out as a scientist.
MacDonell conceding the scientific standard — he could not definitively exclude that the microscopic balls were diluted or had an alternate origin.

Evidence (4)

Informal
OJ Simpson's sock — specifically the outer compression/swipe stain and the microscopic 'little balls' observed on inner surface (surface 3)
challenged — Clark attacked MacDonell's conclusions about origin and timing of the inner-surface balls
Informal
Phenolphthalein (pheno) test conducted August 4th using distilled water and a Q-tip swab on the sock stain
discussed — Clark argued the test itself could have caused the inner-surface balls; MacDonell denied it without experimental support
Informal
Photograph of one 'little ball' shown in prior testimony
discussed — Clark emphasized only one photo existed; remaining six or seven balls documented only by MacDonell's verbal testimony
Informal
MacDonell's experiment on a 'lightweight polyester' stocking with applied blood
introduced then stricken — MacDonell began describing it but Clark objected as nonresponsive; answer struck from record

Notable Exchanges (3)

Marcia ClarkPeter NeufeldLance A. Ito
Clark requested a sidebar to formally complain about Neufeld's repeated loud speaking objections, calling them 'deliberately disruptive.' Neufeld sought clarification on whether 'asked and answered' is a valid legal ground. Ito acknowledged Clark's complaint but noted he had already admonished Neufeld in front of the jury.
heated
Marcia ClarkProf. Herbert MacDonell
Clark walked MacDonell through the scientific method — observation, hypothesis, testing — to establish that his conclusions about the sock balls were untestable and unverified. MacDonell conceded he formed a conclusion he 'could not test' and could not 'absolutely rule out' alternatives.
strategic
Marcia ClarkProf. Herbert MacDonell
Clark asked whether MacDonell performed a pheno test on material similar to the sock. After MacDonell began describing a different experiment (applying blood to a stocking and observing seepage), Clark objected as nonresponsive, the answer was stricken, and on re-asking, MacDonell conceded: 'Not that specific experiment, no.'
revealing

Light Moments (2)

Marcia Clark
Clark attempted mental arithmetic to calculate MacDonell's potential fees at $3,000/day for 11 days, stumbled badly, and audibly acknowledged it: 'This is terrible. This is terrible.' She arrived at $18,000 when the actual figure would have been $33,000.
Prof. Herbert MacDonell
MacDonell explained he had saved the defense approximately $3,300 on airfare by booking discount tickets at $300 rather than $1,409 per trip, volunteering this information while answering a fee question.

Credibility Attacks (4)

⚔ Prof. Herbert MacDonell
financial bias
Clark established MacDonell had been paid $10,500 and would bill at least $10,000 more — implying financial motivation to favor the defense. MacDonell's admission 'I hope so yes' when asked if he intended to profit was the payoff.
⚔ Prof. Herbert MacDonell
failure to test conclusions
Clark systematically established that MacDonell's conclusion about the sock balls rested on visual observation alone, with no controlled experiment to verify the pheno test could not have caused them. His concession — 'Not that specific experiment, no' — was the cross's climax.
⚔ Prof. Herbert MacDonell
inability to exclude alternative explanations
Clark forced MacDonell to admit he could not exclude that the outer sock stain was made at the murder scene (contact with Nicole Brown's blood), that the balls were diluted, or that they were caused by the pheno sampling process.
⚔ Prof. Herbert MacDonell
credential staleness
Clark established MacDonell had not attended a New York State crime lab advisory committee meeting since 1982 and was not involved in quality control — undermining his claimed institutional standing.

Witness Demeanor

MacDonell was measured and explanatory throughout, frequently volunteering context beyond yes/no answers — prompting repeated Clark objections for nonresponsiveness.
MacDonell appeared to resist committing to billing figures, citing a past experience where testifying to a fee amount caused him to be held to it.
No stage directions indicating physical reactions noted in transcript.
