Absolutely not. There are two main reasons why. First, No one should ever be shot simply for possessing a weapon. A suspect must be acting in a threatening way to warrant the use of deadly force. Secondly, and On the flip side, not all responsibility rests on law enforcement officers. The people in possession of realistic replica weapons must be responsible and consider the ramifications of acting threateningly. Personal responsibility is important and if a child is two young to be responsible with something so easily misused, than responsibility falls on the parents.
