This wouldn't be the first time such an incident has happened. I remember an incident a few years back when a bloke got shot dead by the police after brandishing a blank firing western revolver. His relatives told the armed response team that it was only blank firer, but they took no chances and shot him dead. 'Suicide by Cop' happens fairly frequently. If someone is stupid enough to wave about in public, anything that looks like a gun, they deserve everything they get.
