Taser International has developed an extended-range taser. It is a 12-gauge shotgun that shoots a shocking cartridge over 100 feet:
The teases have revealed little actual info, but a Taser press release highlights that the X3 will be the "first multi-shot ECD (electronic control device) capable of simultaneously incapacitating multiple targets." That could put some real scatter in less-lethal shotgun action, but also raises potential safety and abuse questions.
For now, rest assured that the X3 probably won't go off accidentally. A YouTube video shows the device being subjected to electric shocks, and other tests have apparently involved the cartridge "doing 4 foot free-falls on concrete at 20 below," according to a tweet from X3.
