Thanks for the link. That's a fascinating read. Being a Muslim man, I've been stopped and questioned by CBP numerous times when entering the US. It's interesting how they they always seem to ask the same types of questions, in a seemingly friendly manner, but always glancing at the screen in front of them and carefully cross checking everything being said. Would be interesting to get a copy of my own file and see all the notes they've written about the minutiae of my life gleaned during these inquisitions.
