I love the way that a terrorist would supposedly do almost anything to get into the country: change their passport details, get a high profile journalism job, morph into an 8 year old boy... but NOT change their name. It's like the security procedure is run by middle schoolers trying out programming for the first time.
We didn't have any trouble at the border, but it took five visits to the US consulate and about 2 1/2 hours of talking with officials (not including the waiting periods) before our four year old adopted son could be given a visa to travel over from China. This time they did give us the rationale, which was that "we need to assume that every Chinese person is going to try to work and remain in the country illegally". In the end we were let through, with the strict warning that if they find us doing any work, we would be kicked out of the country immediately. Incidentally, this was the guy we'd been talking with the whole time, who knew who we were and was sympathetic to why we were visiting the US. He just kept repeating that "the system says that I have to..." At the border control in Dulles we were all waved through the immigration for US citizens as a group (because of my wife and daughter's US passports) and a couple of officials even offered to carry our bags to the next stage. Every previous time I've been hassled about my reasons for being in the country, so this time felt really weird.
