This can be very serious or nothing, but it still has to be taken seriously, or we could be missing a key to the next attack. I would hope a CIA type investigator had a chance to talk with all of them. An investigator with knowledge of which buttons to push, and what reactions to look for. CBP has some of the behaviorists in the business (they may not know it) but this situation really does take a person aware of the cultural and religious issues to have any chance to read them.
