The watch list really isn't great.
Personal example: My mother is named Roberta and sometimes she gets stopped at airports because "everyone named Roberta is on a watch list." That's literally the reason she was given. How can you put everyone who shares a certain name on a watch list? It makes no sense to me and it's something they really need to fix.
That said, Guns/The second amendment are a cancer on America. So if this helps restrict sales in any way I'm all for it. There is so much evidence out there that banning guns would cause gun violence to effectively become nonexistent. Just look at what happened in Australia in the 90s. You had heaps of people taking the same stance Gun-loving Americans and Politicians are now. And in recent interviews many of those politicians admit they were wrong and that it works.
I'm not delusional though. I know that America's love affair with guns is never going to allow that to happen. So at the least proper restrictions need to be put into place. As posted earlier in this topic, there is a lot of evidence that states with higher restrictions have less gun violence. We should be able to at least get every state to the level of those towards the bottom. We can't keep letting the NRA's greed to persevere over logic. These weapons are too easy to purchase and by nature incredibly easy to kill with. Shootings are abundant and they need to be stopped. People shouldn't ever feel scared to go to the opening of a highly anticipated film, or to school, or to work.
My mom's name is also Roberta and she never gets stopped. Might be something your mom isn't telling you! Or not, the list could very well make no sense at all
