There was a bit more to the story than "just a bullet". There were trips to Afghanistan and Pakistan, Osama Bin Laden candies (really!!), a bunch of religious books and an overzalous customs agent.
There is not much story to this, just an agent who put 1 and 1 together, and came to 3, which to him automatically meant "terrorist". After an interview, the guy was allowed to go.
In the rest of his story he then said his phone was tapped and he constantly got secondaries at the airport.
I'm a little hesitant to believe the FBI/phone tap part of the story, but it certaibly did make for a good read.
