Someone brought this up the other day. Not all police are proficient in the use of firearms, nor are a significant portion of military - yeah, many have to qualify, but then that's it. No more proficiency training. I'd rather it be concealed carry folks, who've passed a better background check than just a 4473 check, and those who can demonstrate the proper proficiency.
“I’d rather it be concealed carry folks, who’ve passed a better background check than just a 4473 check, and those who can demonstrate the proper proficiency.”
Problem with that is it becomes a race to see how many the shooter can take down before the concealed carry finds the shooter. Teachers carrying is a good step, but is a stop gap measure.
The real solution is lock down while class is in session.
