That is what the police are for, they work off duty all over. I caught a shoplifter once that had a gun, knife and parole warrant out for his arrest. He told me that if he had not known that I was law enforcement from prior contact with him, he would have shot me to keep from going back to prison. So strap those rose colored glasses on tight when you leave your house, they may get knocked off one of these days by reality.
