TASER Shockwave

Have you ever had a crowd of unruly people that need to be tased, but only one TASER? Your prayers have been answered! [Link]

The TASER Shockwave is a modular system, letting you bunch together dozens of these TASER X26 stun guns. That oughta keep those evildoers at bay — when they get within 25 feet of this monster, you open up a can of electro-whoopass while you sit pretty with your remote control trigger 100 meters away.
This beast is designed to "instantaneously incapacitate multiple personnel," and is designed for violent crowds and riot situations. So now hoards of people can be simultaneously stunned into semiconsciousness. Since it's modular, you can daisy-chain the units together, stacking them vertically or horizontally for a fierce network of maximum shockage.
