So the gun registry has been in place in Canada now for a few years. It is not a popular topic of conversation, especially in Western Canada. I decided to scour the Internet for statistics that may prove getting everyone to register their guns has resulted in a reduction in murders with guns. I was not successful in finding those kinds of figures. If anything, the rates have stayed about the same. In cities like Toronto, the murder rate has gone up.
I'm not a rocket scientist, but I think making people register their guns (for a fee) only inconveniences hunters and gun collectors - not criminals. If we actually looked at the percentage of gun related crimes committed with registered guns, I bet the number would be quite low.
I suggest the money (approaching $2 billion) be used to hire more police officers.
