I catch the show everynow and then too. Some of the "futuristic" weapons just coming out still have to work the kinks out of them obviously, but it is still neat to watch. My favourite of the new weapons was the directional sound one. I wonder, if you had a frequency, JUST above human hearing limits coming out of that, would it cause massive headaches to the targetted person? Could it cause things like ears to bleed and such, or would it just really tick off all the dogs??
One other weapon maybe they should research on that show is the supposed "gay" weapon that was rumoured to be dropped on the Al Quida and Taliban soldiers, literally convincing them to make love not war!! ;D
