By the way, I'm not against armed guards at schools, and one of the schools I went to 30 years ago did have a police officer (I think he was armed).
Here is something I wrote... think about it, tear it apart.
-----------------------------
Like many gun owners I grew up in a time when we didn’t have mass shootings even though guns were in the trucks at school. It is tempting to blame societal changes for the increase, but the truth is violent crimes are about half of what they were 30-40 years ago.
Furthermore, the psychopath has always been around. The infamous 1966 Texas tower attacker used a bolt action rifle to murder 17 people in a 90 minute period. What has changed is the availability of semi-automatic weapons using detachable high capacity magazines. Back “in the day” very few people even knew such combinations were legal.
These weapons enabled Cruz to murder 17 people in 6 minutes, not 90; the 27 murders at Sandy Hook took only 5 minutes. 107 people were shot in about 10 minutes at the Pulse Night Club, 49 of them fatally. These shootings happen so fast that armed guards make little difference.
This is not the first time we have faced the emergence of weapons with such obvious extraordinary potential for mass murder. In 1934 we enacted the National Firearms Act, which characterized machine guns, short barreled shotguns, etc as class III weapons. They weren’t banned; instead, additional vetting and financial commitment were required to own one. As a consequence they aren’t in every nut’s closet, and crimes with these weapons are virtually unheard of.
On the other hand, there is no special vetting for semi-automatic weapons with detachable magazines. In fact, you don’t even need the scant background check for private party transactions, and a popular online gun site currently shows about 40 of these weapons for sale from private parties in the Bozeman area. I don’t like gun regulation, but these weapons need more regulation than zero.
