I just saw this on Modern Marvels on the History Channel tonight.
It is fired from a 12 gauge shotgun and has no wires connecting the shell to the shotty. Yet the projectile will hit you and still give you a big fat wallop curdisy of Thomas A. Swift's Electric Rifle (TASER) technology.
Supposedly taser international has some thing going on with the US Marine Corps and I don't know about you guys but to me. This is like the coolest thing for applying LL/LTL force without inventing yee old Star Trek Phaser set to stun

And to top it off if you had some one with the special effects and texture skills not only could you implement this in SWAT4 via a Mod, but make it look real too.
