There's a 1min video of what happened. You don't need a Doctor to tell you that this cop
- has way too little or no training on how to de-escalate
- obviously gets off on holding a gun and being mean and threatening
It's all right there, and it can be summed up with "abusive asshole".
Not to speak of the even more obvious fact that he's deliberately withholding ID. Cops, like most public servants, are not allowed to do that.
