How can a policeman pose a risk off-duty if he/she does not pose one on duty? What data shows that citizens with a concealed carry permit pose a risk greater than the armed on-duty policemen in state buildings? What data shows that "gun free zones" are safer than non-gun free zones? As best I can tell, there is no data to suppoert any of this. Imposing regulations for no demonstrable need is arbitrary and basically lawless government.
