Wow!
Firstly, this cop is unprofessional at best, I'm can't imagine swearing and making personal statements are SOP in any force, in fact I imagine they are frowned upon as poor practice. My police friends tell me that their job is to act in such a way as to not escalate a situation. Call scum Sir or Ma’am, and not entering into arguments is part of this.
Secondly, it seems they where under arrest for disturbing the peace I'm guessing. So a Cop can start a yelling match with you, give you "unlawful" orders, give you no reason for the orders, and then arrest you for everything he's created.
Amazing!
Bet, cos of the union this guy ain't gonna get anything more then a slap on the wrist.
