Eugene Volokh and David Kopel at The Volokh Conspiracy report on the Michigan case of People v. Yanna. in that case, a convenience store clerk was charged with possession of a stun gun. Similar to the now defunct Washington DC and Chicago handgun bans, the Michigan law is a total prohibition on the possession of stun guns. The judge in this case held that a stun gun is an “arm” and thus protected by the 2nd Amendment. Total prohibition on possessing such an arm is as much a violation of the Federal Constitution as the city gun bans were.
