I have just heard about this, so details are sketchy, but apparently a homeless man has been shot and killed by police in Vancouver. The man and his friend found a grey plastic toy gun a few days ago, and somehow the police came upon the victim while he was holding that gun and perhaps a beer in some bushes in Vancouver. That is all I have heard so far.
Toy guns can lead to trouble if the police catch site of them. Some are so realistic that there is no way to tell them from real guns. This seems to be what happened today.
