That said, I think people need to recognize that in many aspects what's happening is connected to societal issues that gun control and gun regulations will have very little impact on - remember, even in Japan somebody could make some kind of battery ignited home-made shotgun and kill Shinzo Abe.
Countries with strict gun control enjoy far lower rates of firearm accidents, suicides, and murders. IMO it's clearly worth the tradeoff. Very few of us live in a place where only guns can solve our problems.
The fact that occasionally someone goes to great lengths to kill doesn't mean we should make it easier for everyone.
So let’s define what your definition of strict gun control is. Also, if you want people to care more, stop including suicides because it drastically changes the numbers.
What exactly is irrational?
