I'm not saying this was justified or anything, but, if I were a police officer, accompanied by five other police officers (all wielding guns) and a police dog, and one guy was pissed off enough to take us on armed with nothing but a knife, I'd probably unload as many rounds as possible into him if he so much as scratched his nose. I mean, this guy only has a single knife, and he's not even slightly intimidated by six armed police officers and a motherloving German shepherd. They say he's mentally unstable. Well, to think you could take on six armed cops with nothing but a knife, you'd have to be pretty insane. Or on some kind of drug.
