I know it's sacrilegious to defend the TSA on here, but OP mentioned 3 things that the TSO in question was doing:

1. asking pax if they had any questions about the screening process

2. asking conversational questions like "are you going to Disneyland?"

3. talking about how his son was just finishing a posting to a USAF base.

Which one of these three is a violation of your rights, and how?

The TSA does plenty of things that legitimately deserve criticism, but sometimes I think that people on FT have an automatic reflex that immediately criticizes anything they do. I could post a message on here saying "Today I saw a TSO chewing gum" and immediately people would claim a violation of their constitutional rights and waste of taxpayer money.
