In the five years I worked as a security guard, not once did I have to use force against someone for not having an ID. Sure, some people were very angry. Some people verbally abused me. Some people even threatened me...but I stood my ground and they eventually left. That is all the officers had to do. If the student threatened them in any way or assaulted them, then have at it, but, from the video and the report that I read, that is not clear.
I remember dealing with an incident very similar to this. I stated the policy. Listened to the other person. Stood my ground. And I didn't say a thing. When the person got tired of ranting and raving, they left.
What would you do in your situation, if the person you were dealing with, did not comply to your verbal instructions? I don't frequent bars/clubs, but I'd imagine if the bouncers told someone who was not complying with the rules of the establishment, to leave, and the person refused, I'd imagine he'd be forcefully removed.
If an officer tells someone to turn around and put their hands behind their back and they refuse, is the ofc. supposed to keep repeating himself until the suspect complies? I wouldn't think so. They are now resisting and the officer would be well within their rights, to turn the person around, bring them to the ground, etc., and handcuff them. Of course, bystanders are going to think this is abuse. If the gu listened the first time, it would've been a much easier process.
