That's not illegal even if it were true. And it appears not to be true.
So, if she proved it to be true, she would have a guy getting beat up who wanted way too badly to be a cop. I suspect he's not lying there saying to himself over and over, "I wanna be a cop! I wanna be a cop!..." That wouldn't be illegal. If instead of "Help, Help" he were crying "I wanna be a cop!" does she think that means he should just lie there and let his brains get beat out?
“power hungry cop wannabe”
That is covered in one of the Serino interviews. Serino tries to push George on him being a cop “like on TV”.
George said no. It was because he had gotten letters from his nephew in prison, and how the nephew wished someone had straighten him out as a kid when he got caught breaking the law before it got so out of hand. And George said how he mentors kids, and they all hate the cops. And he thought if he was a cop he could show them a cop that cared about them, etc. I sure hope all of those interviews are in evidence. And I sure hope the defense uses that early interview in their closing statements.
