You particularly don't need 50 witnesses when 45 of them can't testify to the actual accusations, but only to presumed prior bad acts, and ones of which there's no criminal record...which is why they needed 50 witnesses, because their actual case was weak enough that they felt they needed to introduce prejudicial testimony...which the judge allowed???
I learned this stuff watching reruns of "Law & Order"...and I know that has about an accurate portrayal of trial law as a cheese sandwich. And the MJ prosecutors couldn't even manage to achieve that level of propriety? Jacko's going to get off not because he's innocent, and not because he's got a kick-ass defense team...but because he's being prosecuted by a bunch of !@#$ing monkeys.
