The problem is for every responsible gun owner there are dozens of irresponsible ones who are a danger to themselves and others.
Look at all the damn cases of kids killing themselves playing with guns left out by their owners.
Anyone who argues against the idea of gun control shows a distinct lack of empathy at best and is one of the those irresponsible and dangerous users at worst.
Thats citizens of every country.
It's not exclusive to just Canada and the US.
