I really don't see students participating in these drills. I'm all for them. Not even police know what to expect when or IF they go in to stop the threat. The one in Fla stood outside and the one in Connecticut stood outside. The one in Connecticut was waiting for back up, really? wtf!? still wont get over that one. No one knows how the shooter/s will operate. Least these teachers, the ones willing, will have training and know how to react and protect as many of the children zs they can. They are the first responders.
