All humor aside, there's a lot of risk allowing teachers to carry handguns.
Just carrying a firearm doesn't make you competent in marksmanship, stress management, crisis management, fire suppression, threat incursion or coordination with police and SWAT. At the very least, police could mistake an armed teacher for the intruder. Plus, there are unstable people in every profession.
My point is that not everyone should be armed. I don't mind teachers carrying firearms ... but imo, they would have to register their carry weapon so the Principal and law enforcement know who's armed on campus. And they would need annual training in gun safety, marksmanship, crisis management and command & control with local police. They obviously would have to pass a criminal background check and have no history of domestic violence.
As for the 14-year-old saving his mom's life ... that is AWESOME. That took a lot of guts and composure under pressure.
