That's exactly what I mean, kind of hysteric.
Well I suppose that depends on your understanding of the word.
If you mean risible, I'm sure the affected passengers would disagree. If you mean panic-stricken, I thought I'd explained that evacuations are SOP.
Anybody who has spent any time in airports knows just how stupid/clueless some of the patrons are. With that in mind. the security has to be aimed at the lowest common denominator. If there is any flaw, however remote the possibility, then some yokel (or worse) will bust it sooner or later. As in this case, it should simply not be possible to throw the place into turmoil just by going up a down escalator. Put a guard there FFS, there's enough on the payroll. And so on...
