How can I tell if someone trying to enter my house is really a police officer in plain clothes and not an impersonator?
Ask to see identification and call their department to verify their status. This is a reasonable and sensible precaution that you should take before allowing a plain clothes officer into your home. It is unusual for a police agency to take you away from the scene in an unmarked vehicle, so be certain to verify the identity of the persons giving such an order before entering the vehicle.
