You are correct in one point, GZ is not OJ.
I have a friend who was called to jury duty and was asked if the defendant used his/hers right to use the fifth amendment would that effect his/her opinion of the defendant, and my friend said 'yes" and was kicked off jury duty.
Now just thinking, with this prosecutions disasterous case, GZ has the cajones to go against the normal Johnnie Cohchran defense attorney conventional wisdom and to actually testify.
He will have the world watching as he testifies and making his defense, unlike OJ who didn't have the cajones to testify.
The difference between these two cases is that OJ just wanted to win and not go to jail, while in GZ's case the truth must come out.
The truth is coming out without him having to testify and your agenda is showing.
