Employees of the TSA do not have the power to detain a person, confiscate a camera or delete photos - only the small number of law enforcement staff of TSA can detain or arrest someone.

I believe the victim in this case should have pushed for clarity on exactly who they were interacting with - any non-law enforcement employee of the TSA can be flipped-off and ignored outside the sterile area.

Even if arrested, I don't believe even law enforcement has the authority to delete photos arbitrarily - they, along with the camera, would be evidence.

I believe the victim should contact an attorney who handles these sorts of issues pro bono....at this point, the ACLU is basically useless for just about everything.
