Many regional airpors I have been to have no baggage screening or metal detectors for pax screening (and I don't believe they need to). I guess the point some are trying to make here is that breeching the perimeter with ill intent is as simple as buying a ticket and walking on. All the 8ft razor wire fences in the world, even the half built ones have no effect on a ticket holding pax. So I agree whole heartedly that much of the terrorist proofing is just for show.
