With all due respect, while these situations are anomalies, there is sufficient evidence that they do occur.

I have personally been a victim of one of these "interrogations" by US border officials and unbelievable as it may sound, I left the interrogation room (at a Canadian PFI station no less) with a torn shirt and blood dripping down the side of my face because I refused to falsely admit to some allegations made and the immigration officer lost his temper with me. I was addressed with racial slurs ranging from "towelhead" to "sandniger" and told that my passport must be fake because "all you fucckers from that part of the world are named Mohammed or Singh or some other fuked up name". Did anything come out of it? It took over 3 years and a lot of lobbying before I got an apology from the State Department. Due to my line of work, the advice from my lawyers was to let the matter drop as a public airing of grievances would only result in future problems. So I did, but to this day I refuse to set foot in the United States again.

I have also had the chance to read the official account of that incident, and some of the lies and coverups in there make me sick to the stomach. There are comments attributed to me that I never made, documents that are referred to that state completely different things than are stated in the report and even people that they claimed to have spoken to who swear that they were never contacted. Conveniently, the video recording of the interrogation was also determined to be unavailable due to a faulty machine on the day in question.

The only thing that surprises me here is that they finally granted her entry. Most people aren't that fortunate.
