Bloody hell.
As someone who grew up hearing about the [https://en.wikipedia.org/wiki/Hillsborough_disaster](http://www.Hillsborough.com/ Disaster), this is terrifying. There's nowhere near enough crowd management in place, which means that a panic could be tremendously dangerous. I don't remember the people-density above which a crowd basically starts acting like a fluid, but I'm pretty sure this is above it.
