The real policy problem here is that we're talking about mass shootings, which aren't as big a problem as the amount of attention they get would indicate. (Unless mentally ill white person shoots innocent white people is somehow a bigger deal than mostly minority on minority crime taking thousands of lives, and I don't think that's the case).
The reality is there have been 14 mass shootings that caused double digit deaths in the last 35 years. Five of those were terrorism. The rest were mental health related.
Of those 14, 11 of them involved handguns, not assault rifles or any sort of rifle for that matter. (One I'm listing as handgun also had a shotgun, but no rifle).
Even if we defined mass shooting as 3 deaths (and I'm not sure a domestic double murder suicide should be in the same category), and if we include spree shootings that can extend over a period of days, even then we're talking about around 80 deaths per year out of 325m people. Versus about 200 deaths per year from running into deer.
Most gun deaths are suicide. If you could take guns away, then then the cleverly worded suicide by gun rate goes down significantly, but the actual total suicide rate does not. People just turn to other means that are even more accessible.
If we want to have a conversation about access to effective stigma-free mental health services, I think we could get a lot of agreement and society would be a lot better off.
The largest category of non-suicide deaths by gun are from criminal activity. That's the out of control murder rate you're seeing in places like Chicago. That's almost entirely handguns, mostly transferred illegally.
There are smart things we could do about that too which would make the country significantly safer & would not be a knee jerk reaction towards guns that mostly are not the biggest of problems.
CDC has reliable stats on gun deaths compiled from the annual FBI crime stats reports. The mass shooting numbers I cited are updated through Vegas and come from here:
