A Weapon Better than Bullets?

Here is another great idea from Tess Gerritsen. She doesn't suggest this would be a good biological weapon for us to master, but I don't see why not. We would have to change the military uniforms of course; lots of Velcro required. On the other hand, maybe we should spend the developmental money on a mechanical version. Yet again, going the biological route would mean the enemy would have to kill you to disarm you. Hmmm, obviously a lot to ponder here.
