John Lott: Armed teachers can save student lives – Don’t leave children defenseless against school shooters

Twenty years after Columbine High School shootings in Colorado, in which 12 students and one teacher were killed by two students who then committed suicide, Americans are still looking for what actions to take to stop mass public shootings.

The rest of the world, where mass public shootings are actually much more common, is also looking for solutions. Russia, France, Finland and Norway are among the European countries that have experienced far more deaths per capita than the U.S. from mass public shooting attacks.

Change is slowly coming across America. For example, a growing number of states and school districts are coming to the commonsense conclusion that we should not leave our children unprotected and defenseless in their schools.

Florida and Texas are both on the verge of enacting major improvements to their laws that will increase the number of teachers with guns who undergo firearms training to protect their students against attackers as a last line of defense.
