I laid out my opinions in the mass shooting thread. I'll attempt to keep it brief here.
-No conceal carry for teachers in school zones, no militarized police presence in school zones.
-Metal detectors, CCTV of egress points monitored by SRO's.
-Massive increases in budget for mental health services, within schools and for society as a whole. This includes reopening mental institutions that were shuttered due to lack of funding since the 60s. Jails and police officers are not trained nor equipped to deal with mental illness.
-Federal Universal Background Checks for purchase of all firearms, but tied to the individual, not the weapon in question. Ensure it is not stolen, then leave it at that. If no flags come up for mental health, felonies, etc., allow the purchase. Destroy the record of purchase after set number of days. If flagged, allow for appeal within a certain period of time. No limit to appeals.
This is what I was referring to that GrandVol and I agreed on the other day in the Mass Shooting thread.
-The cornerstone of all of this is increased access to mental health services and increased participation of parents in raising healthy children. We can't do anything about parenting, but we can be sure that teachers, administrators, and society as a whole has better access to mental healthcare.
I'm probably leaving some stuff out that I mentioned in the other thread, but this is the gist of it.
