That is BS, the prosecutor absolutely could have charged him, and any deal could have waited for further investigation and negotiation. This was a violent crime and he was not entitled to a no charge diversion program.
I’ve been involved in much less egregious cases and the prosecutors are pit bulls in getting the woman to prosecute, and the judges treat the man as guilty on arrival, and that is in cases with no video and just based on an initial he said she said.
There is no obligation to immediately let a man off the hook when he is brought in for violently striking a woman. Quite the opposite.
Well, since I don’t live in Jersey I cannot answer to the prosecutor’s actions only what he has said in more than one interview.
