There are lots of folks looking for solutions to handle future school shootings. While I'd prefer armed teachers and or armed security, that doesn't resonate with everyone. One of the latest solutions is the Barracuda Door Barricade which is designed to keep doors on lock down in active shooter situations. There are three different models depending on which way the door opens and what kind of hinges it has. Check out the vid:
In concept it seems like a pretty innovative tool, but I wonder how practical it will be. Where would these devices be stored throughout the year? If a teacher or student is in full panic mode would they be able to deploy the device? I visited Bilco's website, the manufacturer of these products, and there was "call for price" which leads me to believe these things are pretty damned expensive. I guess if this was the only option versus nothing at all it would be good, but I just don't see one (or several depending on the number of doors in a room) of these in every classroom in America.
