Original DA had them. Which included a rule of 'no one-hit kills,' something Lugia still emphasizes to this day.

Plus, one of the factions in the RP WILL have them, since they're... pretty radical. Even then, we'd have to pull more than an EMP out of us just to disable guns, 'cause buildings and such still stand. Remnants of the old world.

So yeah. Oh, and there's little chance of being jailed. Authorities will come in later on, though.
