But press a button, and those teeth--six electrified cartridges tethered by 25-foot wires--shoot out in a 20-degree arc. Inch-long probes emitting 50,000 volts of electricity pierce through clothing and skin. If a human being is in their path, his or her muscles immediately flex and lock involuntarily.
