This happened to a friend a few weeks ago in South Florida. A group of local sportbike riders gathered at a warehouse area to race. Un/fortunately, BSO was waiting there and started rounding people up. He was sitting on his bike, not racing, and a BSO deputy pulled him off the bike causing the bike to fall on top of him. He was slightly injured but the bike suffered quite a bit of damage. BSO ran his license, which was clean, and told him to go home. He should have asked for an accident report and started talking to lawyers. Unfortunately the guy doesn't want to pursue the issue.
Of course the incident is different, but just goes to show a lot of cops are just completely out of control.
