Not only that, but even let's say they did not do this at all, I do think (believe it, or not) that if they had a little announcement prior to "releasing the hounds" so to speak I think it would set a different tone.
It's one thing to release everyone and then suddenly shout, "don't run, don't run" as all the guests zoom past everyone and TMs really do nothing against it (more than likely to prevent themselves from getting hurt). However, while it wouldn't prevent everyone, I do believe guests would act differently if TMs did a little announcement prior to letting guests in and would help if at the minimum had a TM 4-5 feet apart from each other leading people to the charge, their arm out if anyone passes.
Do not know what exactly happens now, as I've never been there to see it for myself, but people have mentioned more than once that TMs are involved, but don't do anything, so I wonder where they're walking, or standing when chaos happens, but I have a feeling that if they did even something similar to this, that it might lessen the blow / running a little bit.
