Ah, he was shot in the back.
Stop trying to guess what happened.
Either the bloke got shot because he was behaving like an idiot, or that cop shot him was the idiot & wasnt using his nog. It's probably both.
Eventually the truth may come out.
But its a well known fact that cops are pathetically trained as far as avoiding these 'deadly force' scenarios are concerned. Until things improve I think the instructors at the police training colleges should automatically be charged with manslaughter & left to fight it out in court, after every cop killing. After a couple of years with those sorts of policies, cops will eventually be trained to use their head in situations like this.
Afterall if you shoot/kill a cop you are useally autmatically charged then left to fight it out in court, even if it turns out that it was self defence. Why should cops be treated any differently than anyone else. If they don't like it they can leave - there's always ,many more people applying to be cops than there are positions avaliable.
Anyway if training methods are updated a bit of turnover is actually desirable - trying to train new tricks to old dogs is a near to pointless excercise.
