There are a lot of things the police can't do, but do do and get away unscathed because of union or department backing. I wouldn't be surprised if they beat a person to death for refusing to give this info up.

Personally im not taking a fucking chance. If they ask, I'll provide any info I have. I am trying to live, not demonstrate to a cop that I know my rights he is violating. If you think that's a wrong mentality to have then maybe we should step back and figure out how to make actual progress to de-escalate a police state.
