When he's working, I doubt if he's subject to the same rules pax are.

Violence at the checkpoint is wrong, period. Doesn't matter if it's TSO on pax, pax on pax, pax on TSO, TSO on TSO. It is wrong.

Pax should respect the authority of the uniform. TSOs should live up to the responsibilities that come with their uniform and authority.

If permanent SSSS is appropriate for a pax, it should also be levied against a TSO.

I think the penalties should be harsher for the TSO precisely because the TSO is in a position of public trust and should be held to a higher standard. Just like I believe a TSO stealing from pax (or fellow TSOs) at a checkpoint should bear harsher punishment (loss of job + prosecution) than a pax stealing from a pax because the TSO is guilty of the additional crime of abusing his/her authority and violating the public trust.

I feel the same way about violence perpetrated by pastors, teachers, LEOs, or adults on children.

I think TSOs should be held to a very high standard because of what is at risk. A TSO who resorts to violence is, IMHO, a TSO who is not focused on the task at hand. He/she is a TSO who is jeopardizing my safety by his/her anger management issues.
