So you're clairvoyant now?
IIRC, Parkland shooter called the police and told them he was going to snap and shoot up a crowd. Yes, sometimes it is pretty ****ing clear someone is going to do bad things; authorities should get their butts in gear and get the guy adjudicated a threat pronto (yes, we have laws for that).
That “we need red flag laws” shows the absurdity of expanding background checks: if gov’t agents aren’t going to act on red flags now, disqualifying information isn’t going to get into the background check system.
institutionalize nuts not guns.
“...where there is evidence that violence is about to be committed.”
Wanna bet the definition of “evidence” changes based on the political party in office at the time?
