Again extreme views and bullheadedness on both sides seem to let the problem continue. Some of it is simply culture clash...when I lived in Tuscon the whole neighborhood went out and fired our guns in the air at midnight on New Year's Eve...notice it isn't done in Times Square.
There is little sense in arming an educational staff that we can't even seem to screen the pedophiles and rapists out of.
Think Courts aren't gun free zones? try walking in with one.
Jails? Cops lock them in a box before they enter.
The biggest problem as i see it is entrance architecture and screening. One entrance, guarded, x-ray, etc and built for defense...this goes for vehicle loading areas also. We build like this all the time...courts, gov't buildings, airports, why not schools...it's really not that difficult with the right expertise.
Would it help to have trained full-time armed security at that entrance? Absolutely. Roaming the halls? no.
Do we want armed poorly screened, poorly/non-trained civilians/parents/PTA members taking turns waiting for a chance to shoot a troublemaker.?...nah Hell, even most police training doesn't seem to be adequate for decision making on when to fire and when not to...or when to beat the hell out of a citizen for that matter...
There is a viable solution somewhere if people could just get off their soapboxes and work together toward it...I think all this 2nd amendment and gun reg crap has nothing to do with security of our schools, it's simply more political rhetoric on both sides...same old, same old.
I used to own several firearms when younger, but sold them for my own safety after I started dealing with bouts of depression, and the realization that I have a very vengeful nature...I've nothing against them...just not for me.
