The Israeli's use paintball guns as a non-lethal weapon.I say police should use markers in riot control. Theyre using rubber bullets which have the same/more damage potential than paint, and paint has added benefit of marking them for arrest.
I say use means as needed, including your gat. Just try to aim for centre mass
edited for you..For the intruders sake, he'd better hope the first item to hand isn't the 12 inch rubber dildo I treated myself to recently.
