I can't find any definitive information on this. Disturbing if true.

I can't supply you a reference. It was... maybe 4 to 6 months ago? Border Patrol was doing something more than 100 miles from the border, and a reporter asked them what their justification was for being active that far inland, and the Border Patrol spokesperson said "international airport".

I mean, that could have been just one person's attempt to justify them operating outside their legal authority. Or it could have been what they were told to say, meaning it was somewhat more official policy (or at least official smokescreen du jour). At any rate, it has been claimed, at least once, not in court but to the press.

		If so this was an individual claim, it’s not known to be official policy, the law doesn’t support it, and it hasn’t been used as a successful argument in court. This claim comes up regularly but it’s a misinterpretation/rumor. People should stop repeating it or it will become one of those “folk truths” that eventually becomes accepted and real.
