I think it would be so funny to pretend to be a policeman and chase my friend.
Are you thinking of doing something criminal?
Yeah it is probably a crime to pretend to be cops.
It is wrong to impersonate the police. You could get arrested or hurt someone of you fake it as a prank.
It's funny. They messed with the wrong person.
This is a mean thing to do. If you friend upset you, then tell him that and talk about it. Don't play this joke on him.
