Laura Hart McKinny, a screenwriter who recorded interviews with Detective Mark Fuhrman for a fictional screenplay, testified on three trial dates in late August and early September 1995 in proceedings concerning the tapes and before the jury. She authenticated recordings from 1985 through July 1994 in which Fuhrman used racial slurs and described police misconduct. Christopher Darden challenged McKinny's reliability and her transcriptions on cross-examination, while defense attorneys Gerald Uelmen and Johnnie Cochran examined her in support of admitting the recordings; disputes over the tapes later continued over admissibility, public release, and copyright protection.
