increase rage?
the problem with comparing to other countries is they dont already have millions if not billions of firearms in homes, and hundreds of thousands of illegal ones in cirminals hands. you cant stop that by banning 10 round magazines or guns period. you would have to go door to door and grab guns to disarm this country and even then, you've only disarmed the honest people who arent hiding them where you aren't looking. (helpful hint, those arent the ones who want to shoot innocent people)
how about 10 teachers opt to conceal carry and take training courses. a kid walks into school with a .45 and starts shooting his class mates. teachers A, B, and C hear gun fire and immediately draw and move towards the sounds of gun fire and screaming. teacher A reaches the cafeteria in the entrance to the shooters rear. as the shooter shoots his 4th victim teacher A puts 3 rounds center mass into the shooter. teachers B and C enter from a different location and clear out the rest of the students, who are now alive because of teacher A's heroics, rather than dead because the police are still 5 minutes out. thats a whole lot of rage filled parents who get to hug their kids that night.
