That cop didn't just show poor judgement, she showed that a citizen giving her grief about parking is enough to trigger her. She's in the wrong line of work. Policing is a thankless job and part of it, a large part of it is dealing with the public.
I thought they were hiring people with brain cells (university degrees) these days. Just who are you passing
@jc100 ...
But in all seriousness,
@Rob MacLennan has the right of it. "Sorry for the inconvenience, If you wish to make a complaint my badge number is x my name is x. Have a good day." And begone. No sergeant is going to give a **** about a parking complaint. But being on video and getting in the news about flipping off a citizen will certainly get some higher ups attention.
