So the consensus is there might be a police officer in the vicinity so armed people should run and hide so they won't get killed trying to stop a bad man. They might as well stay home with their gun if they have to worry about that too. Bad guys is bad enough but now we have to worry about friendly fire? What if there is no policeman handy or if he just left his gun in the rest room, can we do something then or should we still run and hide and watch the doofus with a gun shoot people who are exposed. Should we take notes so we can be good witnesses? Inquiring minds want to know.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
