Chris Hayes: I am more certain of this than I have ever been. Stop lockdown drills in all schools...

10. I disagree

I believe they do work. They prepare the students and teachers on how to proceed when faced with the real event and help to reduce chaos. Mass chaos will lead to more casualties. It's unreasonable to think any single act will totally prevent the loss of life but a combination of actions will save some lives. We do these drills at work and I have children in school as well. These drills suck but they are necessary. I don't know how they are done everywhere but in Broward Co. FL., drills are announced as such. Parents also receive a text before and after each drill. I believe this will help to alleviate some of the negative emotional costs and the parents can discuss it with their children when they get home.
Chris should know better because I've watched his program after several school shootings where the students and teachers credit these lockdown drills for saving lives. To compare these to nuclear bomb drills is ludicrous because school shootings have a higher probability of occurring. Thus, through experience, these drills are constantly being reassessed and improved.
