Comment: couple things..

Cheif of Police can't drop the charges once they are filed. At this point only the prosecutor. Or the Judge could jave it dismessed on certain grounds, but he has already found probable cause, so unlikely. And its quite easy to get a conviction if its a bench trial. Only the judge decides as opposed to a jury. All misdemeanors are set for a bench trial unless you request a jury(some states don't give you a right to a jury if its one of the lowest level misdemeanors)

Civil charges are unrealalistic unless you pay to file the suit. Theres not enough of a prize for a lawyer to take up on contingency. And he can't file criminal charges against anyone. He can report a crime and then its up to the DA. And for the witnesses, if your supeonad.. you risk contempt if you refuse. Right to remain silent applies to self-incrimination.
His best leverage would have been to ask for the jury trial of it was an option.
But this is a huge abuse of the law.
