"Mr. Mukerjee refused additional screening"

No. Mr. Mukherjee refused screening in private. It's unacceptable to be unconsensually screened in private without a third party (I.E. not TSA officer) witness. I've refused to be screened in private, the TSA makes it VERY hard for you to do that, and I definitely got verbally agitated. How would you feel if there you were exposed to a significant risk of being sexually assaulted with no witnesses present?

"This is absolutely correct, at this time he was in limbo, he was not being detained, but he could not leave."

That is completely unacceptable.

Once you are threatened with sexual assault, it is unreasonable to expect to be anything besides "aggressive evasive".
