you obviously know the rules and you happen to break the rule of attacking unarmed people without a reason, you know why you would be kicked, no warnings needed.
who fights without any weapons?
Yes, you do need to wear town watch uniform in order for people to listen to you, think about this in modern day, a person with a casual outfit comes up to you and says, 'its the police, i need to search your body for weapons' will you A) stop, raise your hands and stand by the wall or B) carry on walking.
