I would have thought that no special training was required to make TSOs understand that it is unprofessional to make sick jokes when their hands are inside someone's waistband or they are kneeling eye-level with their hands fumbling between a pax's legs. It is unprofessional to hold up personal items and make distasteful comments while they are rifling a bag.

My doctor gets it - I wonder if he figured it out all by himself or if he had to be trained.
