Should he have been tasered, cuffed and arrested? No.

Bit in so many of these cases, like the video here, the cops ask for an ID many times. The cops ask him to take his hands out of his pockets many times. Why would he not comply?

If you won't give them your ID when you ask, they start to get concerned that there is a reason why.

If you won't take your hands out of your pocket when they ask, they will assume the worst, that your pocket contains something illegal or worse, a weapon. That is why they get jumpy and react the way they do.

The cops went too far, no question, but it all could have been avoided if he parked legally AND complied with their requests. Had he taken his hands out of his pocket and given them his ID right away none of that would have happened.
