Policewoman showered with insults: now what?

A video from last year – posted by the driver himself – shows him showering a policewoman with insults at a traffic stop. We have no laws against insulting police (although most people wouldn’t do it because of consequences) and it’s now being asked if we should.

I see why people might think it a good idea, considering the video, but do we really want to make it an arrestable offence to call a cop an asshole?
