A net gun is a non-lethal weapon which fires a net that entangles the target. Net guns have a long history of being used to capture wildlife, stray dogs and aircraft. [1] [2] Recent versions can subdue humans and quadcopters.
The net gun was invented by New Zealander Colin Brown in 1969 when he tried to sell the police a net gun to capture robbers. [3] His invention took off in the 70s but was only successful in subduing wildlife and dogs until recently when a net gun designed for law enforcement use was invented. [4]
