We are always told that certain places are "safe places" and are hammered with the inane question, "why would anyone need to carry a gun in insert place here?"
The reality is that there are no safe places. A man tried to rob two women on the sidewalk in front of a police station. The man threatened to kill them but was unarmed. If he hadn't been bluffing and had decided to make good on his threat the police sitting inside a few yards away wouldn't have stopped him.
You are on your own. You and you alone are responsible for your own safety. When the shit hits the fan make sure the person with a gun & capable of stopping the poo is you. Remember, there are no safe places.
