One of the proposed solutions to school shootings is to arm teachers. In evaluating that proposed solution, one has to look at the long term implications and, in doing so, we will find that the shooter with the assault rifle is crazy (and ready to die for his/her actions). Being crazy doesn't mean the shooter is stupid and when entering that school will take down any adult they may see (and any of our children around the adult) in case the adult is armed. Once in a classroom, any adult attempting to enter will face automatic rifle fire with only a pistol (like taking a knife to gun fight). Remember the crazy shooter has nothing to lose, but our school teachers do. Arming teachers with assault rifles is an alternative, but would be better left to having armed guards and screening equipment such as TSA has in our airports.
The obvious best probable solution is to eliminate assault rifles and do extreme vetting of anyone purchasing a rifle or handgun. It may not stop all shootings, but would just may reduce the number killed.
