A non-lethal weapon inspired by the lightsaber of Star Wars is being developed in the U.S. Unlike the one seen in the science-fiction movie series, it won't really have a laser blade that slices. Instead, it will be like a pulsing powerful flashlight that causes disorientation and nausea. It is thought to be useful for crowd control and other anti-personnel purposes. Human rights groups have expressed fear that it will be sold in the black market and used illicitly. In spite of this, research on the weapon continues.
