However it is perfectly possible for an armed man (or even an unarmed man in some cases) to be legitimately shot by the police if the police have serious cause to believe he has a gun and intends to use it to put lives in danger.
I agree with this - I really do. I believe that if you make laws you should be prepared to enforce them and elsewhere on MN I am arguing in favour of capital punishment. I want criminals executed. I just insist that we make sure they are criminals first and not allow people to be shot for being foreign or for not showing the proper respect.
The omissions in the information released are I think significant. They did find time to mention that he had a gun. They didn't mind telling us that he was in a cab. They were okay with saying that shots were fired. They just missed out the bit about where the gun was found.
It would make them look so much better if they could say the gun was in his hand at the time. Therefore while I am waiting to see, I strongly suspect that they shot him first and found the gun in his pocket afterwards.
While that still could be okay in the right circumstances any reluctance to tell us the whole truth makes it more likely that they don't think it was justified either.
