This character is shown to carry a taser and possibly use it as well.

Taser is a type of electroshock weapon used by firing two small dart-like electrodes, which stay connected to the main unit by conductors, to deliver electric current to disrupt voluntary control of muscles causing "neuromuscular incapacitation". The electrodes are pointed to penetrate clothing and barbed to prevent removal once in place.

Unlike a stun gun, a taser can launch its electrodes, allowing the user to maintain some distance between themselves and the target.
