"90% of everything people do is bungled, postponed, or done inefficiently"

Yup, that's the sad truth. Just read war history books from any war for more evidence of that. People are far better at dealing with ordinary routines than with sudden, shocking emergencies...specially when a certain number of them simply panic and start doing crazy stuff.

One doesn't need conspiracies to cause death on a massive scale...one just needs normal human performance under extreme stress.

Prime example: all those unfortunate people who got trampled to death on the bridge in Iraq.
