Rather than speculate, lets all agree to the following things:
1. Our thoughts and prayers go out to all those effected and affected.
2. This is incredibly sad news, that will, no doubt, lead to a review of current safety procedures and will lead to the creation of even more ways ways to keep Disney Cast Members and Guests safe.
As was said before, over 35 years with no incident is remarkable. Let's not argue about video or pictures or try to be "detectives" and find out what happened. There are specialists, whose job it is to protect everyone, who will tell us what happened, and what is being done about it.
With respect and sadness,
mike.
