And what about the two young German girls that were strip searched in a detetion center because there was not return flight the same day? They were rejected entry because they had not booked accomendations for every night being back packers going on a world trip.

You make it sounds like I've never to the USA. I have lived almost all my life in Canada, have Nexus, went to a top US university, lived in USA almost 3 years of my life. Zero criminal record of any kind. I still got stopped maybe 40-50% of the time crossing the border just to meet my family.

The only "risk" I've ever posed to the USA is having "Iran" as my birthplace in my passport.

no no, it's totally reasonable to ask such question given the recent events.
