It's complete doublespeak horseshit.

Either he did something illegal, at which point they would love to arrest him.

Or else what he did was legal, and they're spouting shite.

This is like when the media says "The suspect refused to cooperate with the law enforcement officer." Translation: The suspect asserted his rights.

Maybe it was the fact that he repeatedly tested positive for explosive residue? But lets ignore that little piece of information because it doesn't conform to the anti-TSA circle jerk that is this thread.
