Chris Darden: Too Bad O.J. Didn't Run Into Fuhrman with that Knife!

Christopher Darden said something pretty shocking ... it has to do with O.J., former LAPD Detective Mark Fuhrman, and the knife used to kill Ron and Nicole.

Darden appeared on the "Reasonable Doubt" podcast, featuring Adam Carolla and Mark Geragos. Darden joked -- we're guessing it's a joke -- that he wished the detective whose use of the n-word torpedoed the case would have bumped into Simpson sometime around 10 PM on June 12, 1994.
