I recently had to board an airplane, and while I went through security people talked about the new body scanners.
Which got me thinking. The terrorists from 9-11 had box cutters that they smuggled through security. Now that would probably (hopefully) no longer work today. The metal detectors are very sensitive and beep at the tiniest steel part.
But most people walk through the metal detector and never get frisked. Only about every 4th person gets randomly selected.
So I thought about weapons that can be smuggled through the metal scanners. Slingshots with stones or marbles as ammo come to mind, but also knifes made from non metal components.
So I decided to make a ballistic gelatin based test: Slingshot and rocks, a wonderful flint knife I traded with Ad'lan from the Zombie hunters, a Cold Steel "Grivory" knife, a Kyocera ceramics knife and a home made dogwood knife.
Should be an interesting test! If the outcome is what I expect (all of these weapons are fairly effective against an unarmed human), then full body scanners and/or mandatory frisking should be employed. Otherwise, terrorists still have options.
BTW, the bands on my CF slingshot are still the originals... made them in March 2010, 17 months ago. They have lost a bit of their color, but they are still fully intact. The Hygenic corp makes some great rubber, that's for sure.
The stones weigh between 15 and 25 gramms, not bad...
