Trayvon's father reported that the police told him what Zimmerman had said, namely that Trayvon came up to him twice, once when he was in his vehicle and again after he had left the vehicle. Trayvon's father said he thought Zimmerman was lying.
What more evidence do you need? Zimmerman is obviously guilty. You only need two witnesses to prove treason, and here we have three.
I’m sure you’re being sarcastic.
If the prosecutors had a duty to disclose all the evidence - even that which refutes their claim - then they are so negligent that it is criminal.
