I don't know about that, but you do see notices all the time that say things like,

"Use of this or any other DoD interest computing system constitutes consent to monitoring at all times. . . information placed in this system is not subject to any expectation of privacy."

It just comes with the territory. Some jobs are more private, some are more public. Bank tellers, customer service reps, talk show hosts, members of Congress. They all get recorded routinely while working, and for different reasons.

Seems to me police interactions are a natural thing to make part of the public record.

That's true of any job: if it's their hardware they can do what they want with it. Tons of jobs have similar monitoring policies.

Unlike bank tellers, customer service reps, and cops, talk show hosts and members of Congress often seek those careers largely because of the public attention involved, not in spite of it.

I can confirm it. Anything you want to release that is even tangentially related to cleared work needs to go through the gov't first to vet it for classified info.

That's not true for life and not true just because you have a TS. It is true for certain compartmentalized programs and their ilk, but a GENSER TS does not bear this responsibility. It merely acknowledges that you've had a NAC and an SSBI performed - nothing more.
