It's pointless ranting about how stupid passengers are for taking hand luggage down the slides. Ranting about it isn't going to change a single thing.
Quite true. But every time there is an evacuation, ppruners come out of the woodwork to whine on about how stupid pax. They make the same comments every time, every single time. They do it because it makes them feel superior. Its rather like the those who, in a crash thread, rush to be the first to post METARs.
