Bruce,
They are no different than most government employees. Honestly, how many government employees have you come across who feel "good" about their jobs? Most that I know are pretty proud of their "hack" status and will continue to mooch off of the government for as long as they can.
I'm not condoning these idiotic, un-american and possibly un-lawfull practices the TSA Screeners are performing, but now that they are government employees they can never be expected to think like "Real World" employees.
