The guy didn't get on the flight.
My theory is those in the terror business want to test the process.
Maybe saying "a street vendor called it in" sounds like we are buffoons and got lucky but I can only imagine all too many areas that are prime to recieve a blast are monitored and we give the patina of being incompetant. IF we show how good we are they won't be careless.
Bottom line is a suicide bomber is gonna be tough to defend but that takes real commitment.
ANd the fact remains this guy got caught. Why not wait right until the last moment to see if he has friends with him or other exposures.
If he got on a plane and left, we could have followed him and see where he went but the reality is he would disappear or be made to disappear to cut all ties. There is value to his capture as well.
Bottom line is there was no explosion and he was nabbed. A threat we thwarted with no congradulatry theme.
Even Jack Baur might not have done better.
