The man had a gun. We don't know what happened. Why jump to the conclusion that there was no justification Nancy66? Because the police are all thugs who are always in the wrong perhaps...? 
That sort of attitude is EXACTLY why rioters can run amok and police were unable to get a hold of it over the weekend. What are the police supposed to do? It's apparently acceptable to criticise and chastise without knowing what happened, or what it's like to do the job. I mean these poor officers are more than aware that it's a strong possibility they're opening themselves open to be charged for hitting the rioters, corralling them, kettling them, touching them...(?!) and the rioters... they know it. So you Nancy66 and all of your ilk, are a large part of this problem in my humble opinion.
I've had enough of hearing about people's 'human rights' for heavens sake. I want to hear more about human responsibilities.
And what about innocent until proven guilty and all that huh?
