We have a collective form of Post Traumatic Stress disorder. As a country, we do. Schools all over are re-evaluating their security plans and practicing drills to deal with intruders. This is a fear response. The drill will not protect us. People who have PTSD are responding to regular circumstances as if they were emergencies. This sounds like us. We did it after 9-11 with all of the beefed up security at airports, schools, college campuses, public buildings, etc. But that kind of measure doesn't address the problem. The likelihood that this terrible tragedy, that any of these terrible tragedies will happen to you or someone close to you is a low likelihood; this is true. I am not unequivocally and unwaveringly advocating for the complete repeal of the second amendment because I'm afraid for myself and those I love; I don't want this to keep happening to anyone. If you can't get any kind of gun, this can't happen, it's that simple.
There are people without their kids while there are people who still have their guns.
