These are SC specialty tags that some retired and some active LEO's will get. Usually for The Wife or Daughter. Most of us look at them as target indicators so thats why I dont have any on any of my vehicles. If this guy was just a security guard, he got the tag under false pretense. He has absolutely no authority outside of his jobsite and if he had escalated on you, the local jurisdiction would have hemmed his ass up. Yes, we do have way too many posers out there ....
