"I'm riding a skateboard, they're riding a skateboard"
Give me a break, if it's against the city ordinance to ride a skateboard on city sidewalks, you're told to stop, the officer calls you over and you run away, you are fleeing from the police. When you physically resist arrest, the officer is going to retaliate. The officer explained it perfectly in the video, disordely conduct, interfering with an arrest etc..
Good thing the kids videotaped this because the dumb skateboarders dont realize it exonerates the officer.
