The only truth in your meme is the fact that the Asian is probably a Republican because Democrat supporters target Asians for violent attacks across the nation.
Only criminals disobey the law. There is NO LAW that would prevent this guy from killing anyone.
Now, the proposals that have been made by Republicans are things like:
More officers at the school...
Locked classroom doors that allow egress, but not ingress during classes in session...
Locked outer doors, or manned by security while open...
Locking up criminals...
More mental health facilities for those who clearly need it...
Better and up-to-date mental case reporting to the proper channels so that when background checks are performed the FBI they can stop little crazy snots from buying them...
Parents...plural. There. Involved. Loving. not in some other State.
No more lockdowns...clearly that didn't help this latest nut that lost his mind. Keep the brats in school and teach them real subjects, not this divisive CRT crap and gender-fluidity bullshit.
Oh, and get off the cops backs already...stop "Standing down" officers. Let them do their damn jobs.
A supervisor told the cops on the scene to stand down and allow swat to do their thing...when they should have kicked the door in and shot the snot graveyard dead ASAP.
NOTHING will stop a determined nut from killing you with whatever they can get their hands on.
For that reason, we MUST be armed to stop them when they flip their lids.
