If getting caught doing so could result in a complaint to the airline employing my security firm, my bosses, and then me, then most likely not. A firm whose customers can quickly replace it with another is likely to employ managers that would fire me quickly for behavior that angers its customers.

But if the people employing me only had the power to do so because they had forcibly taken control of their position, threatening any airline or airport that does not submit to their presence with violence, and threatening others to pay them money so that they can do what they do, then I probably would stop the screening line so I could call co-workers over to laugh at people's stuff.

I'd also probably sleep on the job, complain regularly, treat people disrespectfully, and do all kinds of things that I'd likely been doing all my life leading to my having to work for a coercive mob like the TSA in the first place. In fact, such an employer would be perfect for me since it would have almost no incentive to fire me since its "customers" (or, subjects) can't fire it, unlike McDonald's and the few non-coercive private companies I'd been able to temporarily land much lower-paying jobs with before finding the TSA.
