Diddy will finally face a jury of his peers who will determine his fate for the rest of his life … but finding the right jury — for each side — is gonna be a Herculean task.

The defense will have a much more difficult time, because there’s no such thing as an unbiased jury. Good luck finding a prospective juror in New York City — or anywhere else in this country, for that matter — that hasn’t formed an opinion about this case.

Since the public view is Diddy is guilty, prosecutors have a big edge. As for the defense, the way to go about asking questions regarding bias is NOT simply asking if a prospective juror can have an open mind. The way to do it … they ask if prospective jurors have ever held a view that was important to them but were able to change their mind, and they need to be specific.

This point became a big talking point between Harvey and Mark Geragos on the most recent “2 Angry Men” podcast.

There are other factors to consider … the Cassie video could seal Diddy’s fate, even though he’s not being charged for the brutality seen on the video. But, it certainly tells a powerful story … in TMZ’s latest “Downfall of Diddy” documentary, we presented the case to a mock jury and a number of jurors said their thought process began and ended with the video.

There are also logistical issues … a number of prospective jurors will be excused for hardship reasons — sitting through a 2-month trial during the summer is a deal breaker for many. Many will be excused because they can’t overcome their biases. So the pool will almost immediately shrink.

Race will inevitably play a huge part in the case — it’ll be interesting to see what each side wants in terms of diversity.  Likewise, it’s a dice roll in deciding whether men or women will be harsher/more sympathetic to Diddy.
