What if a thief used a UV light to find and attempt removal of the ID mark?
Chances are, your valuables will end up in local pawn shops or in the hands of police before thieves took the time to scan them with UV light. Once theft is reported, police would be on the look out for your valuables including working closely with pawn shops, a routine process. Displaying Operation Identification decals on doors and windows is a proven theft deterrent.
