Now that is exactly how a police officer should act. There wasn't one other thing he could have done to avoid using lethal force and eventually taking the crazy fucker out for good. I feel for the officer.
Maybe we will get lucky enough to see that one stupid f****** cop who actually let the nutcase grab a hold of him maybe we will get lucky enough to see him actually get his ass knocked off all the way. So what if he has kids! Those aren't kids those are piglets
