Arming and training teacher's in the Us.

We've seen the news about school shooting, a lot of people dead and it's tragic. But what if every school across the US had the teachers armed? We can avoid having 17 people dead and instead have 1-2. One of them would be the attempted school shooter who was stopped by a teacher trained and armed to defend their students. My hope is that with this people will stop shooting up schools and instead protect our students from anymore harm.
