“Any other questions?”
Are you a cop? If so, how would the chief view such behavior from his officers? How would the community that employs you and the chief view it?
I am not a cop. Anymore questions?
The headline ask “Can...?”. The answer is yes. If it had asked, “is it lawfully permitted” or “does it violate the fifth amendment”, then the answer would be no. But cops can and do retaliate.
