Biggest problem here is complacency.How many people actually listen & take note of any safety instructions during the briefing? VERY FEW mainly due flying being so cheap these days everyone has done it several times & nobody really thinks it's gunna happen to them (crash) so even though they may appear to be watching/listening that guarantees nothing! In a true panick situation 99% or people will be thinking only one thing, how do "I" get off this thing & fast!
Placing ABP in an emerg exit row is just to appease the rule makers, nothing more as ABP can panic just as good as an old lady!
