Fuck that, this is when it is 100% OK for a cop to shoot. Fuck tazers, fuck pepper spray, fuck a baton. The man is eating someone else's face on a highway........naked. If you are that far gone, then fuck you. There is no "ethical argument" around this, the man was eating off another mans face, EATING HIS FUCKING FACE, humans don't do shit like that. Not to mention after being shot once the man continued to eat the other dudes face WTF!!!!!!!!! Shit if you told me a civilian shot the man I wouldn't give a fuck. I honestly can't even believe there are people in this world that don't think this man should have been shot, anyone who does is a god damn idiot. Imagine you're the guy who's face is being eaten by a naked guy, I'm sure who would want the man dead.
