Claim 11:
12. A facility having restricted firearm usage comprising:
a facility area;
a signal transmitter configured to emit a signal covering at least part of the facility area, the signal selected to be a predetermined signal operable to deactivate a cartridge of a firearm having a signal receiver operable to receive the predetermined signal, the cartridge of the firearm operable to fire when not in the presence of the predetermined signal;
a plurality of firearm cartridges, each of the plurality of firearm cartridges comprising:
