Why not make a gun that shoots bullets that have a rather large core of Rubidium or Cesium with say a thine copper jacket that blows off inflight thusly exposing the Rubidium or Cesium and causing big troubles for the poor guy who it hits. As it would virtually be melting in the air and burning then it hit and be explosive. or similar with a core of radioactive material with a jacket that keeps the ammo completely fine for the soldier carrying it around. That when radioactive material hits its a guarenteed kill. Plus probably further damage to others. Now im not suggesting that anyone do this. But im just wondering. Why hasnt anyone. People are so worried of chemical attacks and nuclear problems from iran and other. It is portrayed that these people are without morallity and such. But why arent they doing things like this. It would be virtually less problematic for the world. What is it? 3 nukes and we get a nuclear winter from the dust. There really wouldnt be any problems with using these. Maybe the radioactive one. So why dont people do this? to expensive to do? Not easy to do? or is it against the geneva convention or something? That any side caught doing such things would be in big trouble.
