Re: A gun is involved in every single mass shooting.
@TimmyB - Have an upvote for this : "If you really want to stop killing then you need to ban pistols. "
No use beating around the bush, that is exactly what is needed to solve the issue. Just look at the situation in Australia, Japan, Europe etc and realise that what is needed to prevent all those shootings and deaths is to have the same sort of gun laws as countries that don't have so many shootings and deaths.
"that's simply not going to fly in the USA"
Unfortunately that's the current case, but that doesn't mean give it up as a lost cause. And starting by smaller restrictions now is at least a step in the right direction
