It is critically important to have the conversation with your kids. If they are in a lock down at school and they hear gun fire, they get out. Period. Break a window, blow through a fire door, set off alarms, disregard the BS the teachers are telling you, and get out. Period.
I have instilled in my kids that if they are in school and hear a gunshot, they are going to die if they do not get out. No kidding. Run away from the sound.
Unfortunately this type of massacre will not take a lot of effort. The sheeple will not fight back.
As I was writing this, it occurred to me: Are we the only animals that gather together when there is a threat? Most animals I’ve seen will run away from a predator. We train our children to come together and become easy targets.
