I can see this device being very popular with police forces.
>>Made by Arizona-based Wrap Technologies, the BolaWrap is a battery-powered electric razor-sized device, which single-use recyclable cartridges are loaded into the end of. Each cartridge contains a propellant in the form of a .38-caliber partial charge blank, along with an 8-ft (2.4-m) Kevlar-cord tether that has grappling hook-like metal barbs at either end.
When a suspect is fleeing from an officer, advancing on them, or otherwise exhibiting dangerous behaviour, that officer aims the BolaWrap at the person’s arms or legs – they’re assisted in that process by an integrated green laser.
Once they subsequently press the trigger, the cartridge ejects its tether at a speed of 513 feet per second (156 m/s). That tether then travels through the air up to a claimed distance of 25 feet (7.6 m), ultimately wrapping itself around the target’s body one to three times. This trips them up or temporarily keeps them from raising their arms, allowing officers to move in without harming them.<<
