Guilty or not, this seems more like a kidnapping than an arrest. Can they really ignore all rights as they see fit?
Please outline the rights that were denied to him. The article that we are commenting about seems to have a completely deluded sense of what his rights are, but maybe we can start the discussion around his specific rights. Contra the original article, a 23 year-old does not have a fundamental right to talk to mommy and daddy once arrested. Law enforcement is under no obligation to arrest you as you arrive in country…
But the key advice is Do. Not. Say. Anything. other than "bring my my attorney". Remember that in the interrogation game, the FBI gets to lie, but it is a felony for you. The FBI also refuses to videotape interrogations, gets to write the reports, and has played this game far more than you.
Add that up, and admitting that you like ice cream is dangerous. This can be especially dangerous for smart people, who will tend to start thinking about the questions, trying to guess where they're going, what is important. Don't. The rules are stacked against you, you're missing important information, and your interrogators are (probably) practiced experts at creating little set-piece dramas to manipulate you.
