The tool, called the BolaWrap 100, fires a Kevlar cord that ensnares an individual’s body to restrict mobility, giving officers seconds to swarm the person without using more drastic measures such as a Taser or gun. The handheld device, made by Las Vegas-based Wrap Technologies, sounds like a gun when it deploys a tether to entangle someone between 10 and 25 feet away. Barbs attached to the end of the tether grab hold of the person as it wraps around their arms or legs.
