Strangely, I doubt terrorists with bioweapons or dirty bombs will

Is this as more "We've gotta do sumpthin', just to say we are

I think the point is that the DHS gets time to vet the people coming in so
it doesn't have to be done on site by the customs people.

It is really little different than what the airlines have to do and they
block folks from flying all the time. If this actually stops a terrorist
attack it is hard if not impossible to ever tell.
