I've often said that behind/above every bottom rank TSO guilty of misconduct is a hierarchy of lazy/AWOL/complicit upper level TSOs/managers who enable the behavior and are just as responsible as the offender facing the pax.

If a manager made it clear that s/he would get off her/his lazy butt and wander through at random times, disciplining anyone barking and also disciplining any LTSO/STSOs present who didn't address the misconduct, there wouldn't be any more barking.

If a manager occasionally chose to review checkpoint tapes, perhaps s/he would start identifying and addressing the issue of TSOs standing around jacking their jaws and playing on their cellphones instead of performing a useful duty. They might observe (and address) pax experiencing long wait times for a grope when there are plenty of TSOs standing nearby doing nothing.

It's like yelling at the dog pooing on your driveway. The one who really deserves a boot is the owner at the other end of the leash allowing it to happen.
