I'm usually the first one to stand up against police brutality, but honestly I don't think the officer did anything wrong here. Yeah he may have lost his cool too fast, but the way that lady was acting on a busy road, it really wasn't out of line imo. Who cares that she is a great-grandma? It's not like she has a walker or something... she was speeding, acted like an ass, and resisted arrest. Book her!
When I first saw the video, I thought the cop was right, but after reading this post, I agree - he lost his cool. Sometimes cops think it is their duty to teach people a lesson, but they are there to enforce the law. First, he could have noted on the ticket that she refused to sign it, dropped it in her car and went on his way. People refuse to sign tickets everyday, and there is a protocol to follow. Next, once she was out of the car, she said should would sign the ticket, he should have just let he do it and went on his way.
Cop was right in this instance as far as I'm concerned. The lady was resisting arrest and knew full well she would be tased if she kept it up. Too bad. If you want to act like that and not obey the cop then you deserve it no matter how old you are.
