No one did anything stupid or anti-social. en.wikipedia.org/wiki/Crowd_collapses_and_crushes

When people are packed so closely, if there is some push from behind, maybe just someone else trying to squeeze in, people fall over en masse like dominoes and are unable to regain their footing. The people at the bottom are unable to breathe because the are unable to expand their chest to draw in air.
