Exactly, the prosecution can paint GZ as a racist, dig into his past but the defense wasn’t allowed to do that with TM (show character).
I also believe it is immoral to throw in other charges after the defense rests. You put on an entire case for charge “A” only to be judged on charge “B”. Complete BS.
That was the plan, don't you think? The State had no case, so they had to trick the Defense somehow. Let Defense believe in LAW, and that if the court and prosecution agreed to stick to the one charge, that means they would do so.
Then, when you spring it on them, there is nothing they can do about it.
It's not some unrelated charge, it's based on the same set of facts. The manslaughter charge is just murder 2 without the "depraved mind". The same set of actions hypothetically applies, and the same defense applies.
If it were some unrelated charge to which no defense had been presented you'd have a point, but it's not like that.
