I have a client whom I often meet at MIA where she works. While signing in I noticed the security guard had a badge that said "TSA TSA TSA" so I inquired what it means and asked if he is part of TSA. He explained that most of their art gets shipped by air and that in order to insure the integrity and chain of command of the art, one must be TSA approved to appropriately ship the art by air. So technically he is not TSA but he has to display TSA training and certification in order to walk the art through airport security and onto the appropriate flight. He likened it to evidence in a crime and their chain of command. All I can say is WOW!
