I am not comfortable being locked in a building.
As commented on in another thread about this subject...no one is locked IN, late-comers are locked OUT, unless they are "approved" by whomever is "guarding" the door. It makes some sense I guess in more urban areas, and maybe even in some rural areas. In a small rural town of only a few thousand close to my location a woman teacher went out for her normal Saturday morning jog and disappeared, only to have her body found in a shallow grave nearly two hundred miles (U.S.) away with forensic evidence of gang rape, and death by multiple stab wounds. The increasing criminal element coupled with the increasing laziness of law-"enforcement" is one reason I legally carry concealed now. FedUp ain't going down without a fight!
