Agree with the sentiment, especially when applied to computers, though i'm not sure how it applies to non-IT based security, because I just don't know enough about the subject.
> It's another step of security theatre; they need to look like they're doing something otherwise if something happens they're afraid of looking like idiots (despite their measures being completely and utterly useless).
Agreed. On a slight tangent, base jumpers are more than able to gain illegal access to tall buildings in the city, with all their secretive security measures. There are a couple of documentaries out there on this, one I'm confident was shot post 9/11.
My greatest concern when reading about or watching these incidents is the poor treatment of those non-violent citizens taking the photos. Ok, you have to do your job and check their photos, but why not crack a joke, apologise for the inconvenience, and check the photos quickly as possible.
