the trial that he didn't testify because his review of the case found no criticism of the testing conducted by gary sims or dr. robin cotton. the testimony of defense non-forensic expert dr. john gerdes—in which he raises doubt about most of the dna evidence via contamination—is omitted by the defense in all of their post-trial publications about the trial. this would be despite the fact that jurors mention his testimony in justifying their reasonable doubt on several occasions, especially in their immediate post-trial interviews and in their co-written book, madam foreman (1995). unlike the other experts in this case, gerdes did not enjoy publicity from the trial because his claim that forensic dna testing is unreliable was not true. this abandonment by the dream team of gerdes' contamination claim after the trial made the jury defending their verdict untenable. subsequent portrayals of the trial in the media often omit his testimony as well and none of the defense attorneys retained him again, including scheck and neufeld. geraldo rivera asked three jurors what their reasonable doubt was concerning the blood found next to the bloody footprints near the victims. photos of the crime scene show that the blood was there hours before blood from simpson was taken, thus it was not planted; the blood was collected and shipped directly to the state department lab, not the lapd lab, thus contamination could not explain it; the blood was testable, thus it was not compromised. foreman amanda cooley responded that she had no explanation for that incriminating evidence and such did not factor into their reasonable doubt decision, implying she ignored it. juror marsha rubin-jackson responded that she believes simpson's blood to have been left there next to the bloody footprints prior to the murders happening; however, defense never suggested this and simpson said he was never there that day. juror carrie bess responded that she thinks the blood belonged to simpson's children; however, dr. cotton said that the chances of it being anyone else other than o.j. simpson was 1-in-9.7 billion. lionel "lion" cryer lionel "lion" cryer was one of the jurors who came out strong for simpson's innocence during deliberations and afterward. he was especially known in the media as the juror who raised a black power salute after the "not guilty" verdict was announced; an act that generated considerable controversy. however, in interviews in the 2010s, cryer stated he does now believe that simpson is guilty of the murders. he admitted that what he thought at the time to be reasonable doubt of the dna evidence really was not. he stated that a portion of the trial dragged on longer than most people realize. in media portrayals, the dna section of the trial is shortened to just the important clips, whereas the jurors had to listen to 8 hours a day for nearly 9 weeks of technical terminology that was difficult to follow. he admits that the jury not reviewing the dna evidence during deliberations was a mistake, but states that such was because most of them have voted to acquit during the initial straw poll, and the two hold outs changed their mind quickly so further review of the evidence was not necessary.
