At that moment, the terrorist is attempting to deceive the TSOs performing the screening, so that the terrorist's "contraband" is admitted to the sterile area despite TSA's regulations forbidding that material. Thus, there is an immediate attempt to deceive that a BDO
could detect. In theory.
Whether or not any of this makes sense in practice is, of course, another matter entirely, which has been beaten to death in many other threads.
But I'm clearly losing on this discussion, so I'll lick my wounds and leave the battlefield ...
