Now there's the famous question: "Aren't they supposed to hurt?"

Well, I myself think they should redesign the cartridge, if the point of stun guns is to debilitate the target, then maybe these 5 minutes of unceasing shock is not such a good idea if they'll need the victim "healthy" and sane afterwards.

Anyway, wireless stun guns may come in handy to the authorities and whoever needs them. And they're always good, as they don't kill people.
