After the school shooting in Florida, a teenager in Wisconsin by the name of Justin created a device that might just save lives. He calls it the JustinKase:
“I put myself in … a situation saying, ‘OK, what am I going to do to keep myself and my friends safe when a shooter comes in?’ I just thought, this is something I just have to keep going after.”
It slips under the door and latches to the door jam keeping the door closed. He also says it can't be shot out by an attacker.
Justin's school has since ordered 30 of them, one for each room in their school. What a great story!
