I think the police did a good job until the point they shot him.
Why shoot him???? If the two of them can’t handle him, let him go, call back up and arrest him with more police. It’s not like he going to get far and you can tail him.
It’s not easy handling drunk people and the dude could of been on some other shit too but if Your average bouncer/bartender can handle it the police officers should be able to handle it to without resorting to deadly force.
