There have been many times I have stood in that mass of people in the hub and it is certainly not pleasant. It's bad enough that you can't move, no matter what direction you try to go, but to have less than pleasant guests (and who can blame them?) swear and yell at each other, only makes it worse. You are certainly correct that in a panic situation (fire or other emergency, etc.) mass pandemonium would happen and trampling deaths could certainly occur. I know it's something folks would rather not think about, but sometimes those post fireworks crowds terrify me. I fear for the day something like that happens.
That said, this is a major safety issue that Disney needs to address before it's too late. Crowds after fireworks are inevitable, but there should be more CMs and a better traffic pattern to alleviate them. They are simply not doing this in Orlando.
I'd just love to see Bob and Willow during this madness on a busy night like regular guests (ha! like that would ever happen...) and see if something would be done.
