Now, I’m not that alarmed. People can make weapons out of anything. A number of years ago, I saw a violent action adventure–bang-bang-shoot-'em-up movie. In it, a group of very, very bad prisoners were being transported via airplane. The first act of violence occurred when one of the prisoners used a spring-loaded toilet-paper holder to shoot a bullet at someone. Talk about lethal construction from odds and ends.
Having taken Prison Fellowship volunteer courses in the past, I can attest to being amazed at the cleverness that goes into a lot of criminal activity behind bars. This points to the fact that we’re created to create. Being human, I can also attest to all of our penchant to do evil.
There are very bad people out there. Have people used this technology to construct something already? I don't know. Is it wise to promote this? Time will tell. In the meantime, I wonder if airport security will have to go back to tweak their invasive body scanner to make it sensitive to paper, too.
