Homicide bombers, didn’t have anything on them, so it didn’t matter if they got caught.
I'd make it my business to see to it that, the next time someone tries something like this, it does matter -- to them.
Specifically, anyone blows through Customs like that again, I'd have a crew waiting a quarter mile up the road with very specific instructions that if a car tries to overrun Customs, they are to turn it into a colander and not stop firing until nothing, absolutely nothing, is moving inside that car.
