You're aiming a gun at a person who's job it is to arrest you because you've just robbed someone at gunpoint? What would you do in that situation old chap?
There will probably be riots about this but if you're stupid enough to pull a gun on a police man, replica or otherwise then you deserve to get shot..
It's tragic yes and I hope the chap rests in peace but IMO the Cop is not at fault and anyone who does this is gonna get shot, black or...
