That said, airport perimeter security is pretty high on the list of things it does make pretty good sense to care about. After all, he could have been carrying a bomb :)
I wonder whether technologies like Oculus might change the effectiveness of security cameras. A single man could theoretically "be" in multiple places at one time from a security perspective. And the sense of actually being on-location, as opposed to having something on a screen that can be ignored or missed, might return that multiplier to monitoring a location using a network of video cameras streamed to somebody's headset.
Implementation of more automated surveillance to help SUPPLEMENT (not replace) existing security guards watching monitors is ideal. It'll be interesting as security ramps up to include things like facial/ body recognition.

If someone were to just hop the plane and plant a bomb and conceal it, it could be easily overlooked by any observer.
