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.
The Obama CDC study on gun control concluded that guns are used to stop far more crimes than they are used for in crimes. It concluded that a household with a gun saw far less bad outcomes than a household without during home invasions. It concluded a lot of things that didn't sit well with the left, so after all the fanfare to make it, it was downplayed by that admin. Read it, it's quite interesting.
Think through that a bit.
Citation please. NCVS data puts defensive gun use around 70K instances per year while OJP.gov data puts firearm crimes in the 400K range.
