Personally, I never understood why people feel they have to carry on so much stuff on an aircraft. People take huge amounts of material and storet it over the heads of passengers (that could be projectiles in rough weather).

Additionally never understood why the security folks let passengers and the airlines do it....since it poses a significant weak point for those wanting to do bad things. I suspect its mostly a profit thing for the airline companies....as it allows them more cargo space below....for commercial shipments.

If there was less or no carry on items....it would free up security to pay attention to other items that may be brought onboard....as in this case.
