The problem here is that he was pre-selected by the Behaviour Detection Officer (BDO) while in line and then the TSA claimed he rang their bell for explosives.

We can't assume that government agents are on the up and up. Their word is open to question if they have no proof of their claims. Since they don't deny the story, I tend to lean to Mr. Mukerjee's perceptions as a more accurate account of the day.

There is ample evidence that local, county, and state law enforcement will trigger false positives to provide justification for searches.
