But 33% of them involve AR's.
Totally hot take here. In no way am I saying we need to ban handguns or rifles and shotguns used for hunting. If you want personal protection or look forward to deer season I'm all about it. As a kid my preference was duck hunting but I spent plenty of time in a deer stand so this isn't someone wanting to ban guns.
The thing about an AR, it wouldn't have been banned in 1994 so it's not defined as an assault rifle. But we have a generation or two who grew up playing video games with cool weapons and it looks cool. Heck, when I was a kid bb guns looked like standard rifles. You pump you shoot and it was fun. A few years ago my former BIL and I were in a local sporting goods store and the bb guns we saw looked like assault rifles but they shot plastic bullets instead of lead or copper. I thought it was funny at the time because the guns looked way more lethal but were way less likely to shoot out an eye. But a generation of kids grew up shooting them because they looked cool and yesterday a kid who probably had one when he was 10 killed a bunch of 10 year olds with a gun he thought was cool.
Again I'm not a person that wants to ban guns but maybe we stop making this one. It really serves no purpose other than it looks cool. No one is going hunting with it and it's unreliable for self defense. But it is slick looking. If you own one privately that's fine. Stop making them and it becomes more valuable in your collection, but that also means you aren't likely to sell it to a kid who wants to do something stupid.
It doesn't solve the problem but it keeps kids with issues from getting their hands on one.
Everyone seems to have different statistics based off of different criteria, but I think your numbers are a little high. This
link shows that only 16% of mass shootings have involved assault rifles, and not all of them were AR-15s.
I'm not a gun expert, but it's my understanding that the AR-15 is the most popular rifle in our country. There are over 20 million in circulation. There is a coolness factor, but they're also highly customizable. There are a lot of similar guns that would step in to take its place if it were banned.
As I mentioned earlier, it may be prudent to raise the minimum age to purchase an assault rifle from 18 to 21. It's kind of odd that an 18 Y/O can purchase and AR-15, but they can't buy a six shot revolver.
One last note, the 2A had very little to do with hunting. It's primary purpose was to allow our citizens to protect themselves from enemies foreign and domestic. Our founding fathers wanted our citizens to have more power than our government.
I understand that change is needed, I just hope the change we settle on has a minimum effect on lawful gunowners.
