The Pentagon has released its wish list of dream weapons it would like companies to design and one of them is a "nonlethal warhead of miniature organic precision munitions." Or, a magic bazooka bullet that can close in on a target in 20 seconds and incapacitate it without killing it, hovering in midair, poised to strike, like your big brother's finger when he would play that dreadful "but I'm not touching you!" game. It's part of a larger program that the Pentagon is pursuing that incapacitates "targets" (aka "people") through more subtle means: "mechanical...acoustic; chemical; electrical; or dazzle" instead of killing them.
