It's because do you really think that's going to stop these crimes from happening?
What happens if they take your guns "for safety" and some cac still shoots something up because guess what, they don't believe laws apply to them anyway so they didn't give up theirs
As someone said before, these mass shooters ain't running around with some old glock stolen 10 times over. These are privileged cacs with resources we talking about.
America ain't going to do shyt that actually addresses the problem cause that would mean it'd have to address the ugly truth they been ignoring since this country was founded
