What about the dumb ppl running over others trying to get in? not stopping to help?
As Pit pointed out, this has happened periodically going back many decades, it's not a function of this new selfish "me" generation that people keep hearing about. It's been human nature for a long time.
Some people got knocked over, some people did stop to help and that just congested things more and many of them got knocked over. My guess is that many of the people doing the pushing in the crowd were probably unaware that people were on the ground 10 feet in front of them and they just kept pushing forward...
