Well, the ninja baine reference was an admittedly weak attempt at alliteration. Due in the main to having recently seen the last Batman film.
The mention of my concern refers to the subjective feeling I have about personal safety only. That is simply because risk has in fact been greatly reduced beyond the gate, but in many airports around the world, not before that point.
As to not catching all scenarios, I know a spook who trains in the fight against bad guys, and he got through a number of security checks before being pulled up in transit at a US airport with something standard issue. He forgot he had it in his carry on.
I'm aware of the potential of breaches. However, terrorist acts are often designed with a view to terrorising. This leads me to a different calculation of probabilities.
Events like this one are problematic because they can have an affect on public confidence. I may be wrong, but I think that might be just as much a consideration as failure of purpose in this situation.
> If we learned anything from 9/11 isn't it that control of a plane is a significant force multiplier?
If we learned anything from 9/11 it's "they're going to crash this into a building, might as well take them on - there's 100 of us, they can't shoot us all before we get to them.
PS I did not get lucky with google and ninja baine. Is that some new hipster meme?
