...how to realistically prevent yet another mass murder in the US (hint: it's not beefing up hotel security).
Do tell?
Sensible regulation. Pretty simple really, and there are vast lists of things more regulated than guns in the US. A vast majority of people support it. When the NRA lobbies for allowing people on the no-fly list to be able to purchase guns, when they lobby for removing obstacles for the seriously mentally ill to purchase weapons (something Trump signed in February), when they lobby against waiting periods and strong background checks and closed loopholes for restricting unmonitored sales and restrictions on devices to make assault weapons fully automatic and restrictions on large capacity magazines, and when the politicians who are in the NRA's pocket go along with it, nothing gets done. The tired arguments by second amendment (reminder -- written when guns were single shot, it took a while to reload, and guns were a necessity for feeding and protecting one's family) absolutists just don't hold up, and they are in the minority. The slippery slope "they're taking away all of our guns!" argument is bull#$%* and doesn't hold up either.
Before anyone #$%*s their pants, I'm not against gun ownership. I don't hunt, but my brother does, and I have fun target shooting. But regulations and obstacles on the seriously mentally ill won't affect my brother and his hunting one bit.
But you probably know all of this, it's not like anyone with half a brain hasn't heard both sides of the argument and I'm not going to be baited into some #$%*ty name calling rant. Fifty-nine people are dead, and idiots like Tomi Lahren are arguing that if more people had guns they could have prevented it. I keep thinking maybe this will be the one where something actually gets done, but most likely not.
There you go, have at it.
