I did say that they only time they function on the checkpoint is if they have a "pull" (a person of interest). Our BDO's will do the bag checks, but have a CP TSO do the wanding. My main point is that BDO's do not spend their shift functioning as a TSO on a CP. If a pax comes thru, and gets screened, it is a regular CP TSO doing the screening, not a BDO. Everyone on here thinks that if a TSO is being friendly and making small talk, they must be a SPOTnik. I am trying to stress the fact that a BDO does not work as a TSO on a CP, so perhaps people can know the difference between a BDO and a friendly TSO.
