Honestly- I didn't see the video in the same light as everyone else did.
One, these guys chose to get a ticket. They passed a Trooper on purpose on a public roadway where presumably the Trooper was already doing the speed limit, resulting in getting pulled over for speeding. Not a shocker. And being as how they made a point to video the vehicle and the driver, they weren't unaware that he was a cop. All State Trooper vehicles in Alaska have a license plate starting with "AST". Not really unmarked, if you're paying attention.
Then they stuck a camera in his face and proceeded to treat him completely disrespectfully. To expect anything other than to have the book thrown at them was idiotic. I don't see how the video proves they didn't do anything they were ticketed for, as it's not videotaping who they are following or what their speed was, the sole purpose of the video was for a couple of punks to be disrespectful to a police officer and then post it on YouTube.
I don't think the cop was brutal or out of line. I think the kids were. Not surprisingly these are Gen Y kids- a complete failure of a generation, if you ask me. No respect, no discipline, and complete punks.
