This sounds like a "just doing our duty" argument.
If you work for the TSA you're not just contributing to the problem, you are the problem.
If you work for the TSA you're not just contributing to the problem, you are the problem.
What makes this more damning is any TSA employee made a conscious choice to do morally reprehensible work. They had a choice. No one forced them to do their job.
In this light, the TSA employees come off as more morally bankrupt than military officers that had a gun to their head. They choose to be active agents in destroying society in trade for their own comfort.
