When the sheepdogs turn on the sheep, they must be ruthlessly removed from the pack. These sheepdogs turned on the sheep, plain and simple.
The guy was a student at the university library. He had every right to be there. Okay, so he didn't have his student ID with him - not horribly uncommon, especially in a big university.
So the courtesy patrol asks to see his ID card (reasonable) and he doesn't have it. The courtesy patrol asks him to leave, so he saves his work, and he's heading out of the library, which is a VERY large building.
Suddenly, two cops walk up to him and grab him. He resists, as any one of us would when someone - cop or not - grabs us for no reason. Next thing anybody knows, they're tasering the kid, then telling him to stand up. Then they taser him when he doesn't or can't stand up.
I'm a Federal LEO - these cops need to be fired.

We don't know the full story of what led up to the tazor. From what I observed the kid was disturbing the peace before they tazored him. That would seem to be reasonable cause to ask him to stop.
I am curious as to why they tazored him for not standing up.
Then he had no right to be there. Period. That's how it works. It's like driving without a license. If you are caught, they charge you with driving without a license if you can't produce one. If you produce one in court, then they lower the charge to not producing a license.
University libraries are expensive and students pay a very large fee for the priveledge of using them. The University has the right to insist that people who are there are able to prove they are there. If you happen to realize you left your card at home (and you need such a card for everything at the University these days) you suck it up and leave.
Note that when the officers returned, the little punk had still not left.
Then you ought to know better than to depend on only one side of the story for your "facts".
