I'll probably get downvoted for this but what the hell. I've been to the US countless times over the last 30 years both on business and vacations. I have never had any hassle from either the guys on immigration or the customs guys though I did once get asked a domain knowledge question by immigration related to the purpose of the visit. And I'll be going there soon on vacation. It's true that this time I'm taking a clean laptop rather than my normal one but that's the only concession I'm making to their increased paranoia. I would probably be more trepidacious if it were my first visit though, as they would have no previous history.
Having said all that, I hope the guy gets it sorted PDQ, though I wonder if there is more to this than 'security guy gets nabbed by the Feds for no apparent reason'
