The problem with witnesses statements is that it was a chaotic and emotional situation. Humans are irrational, especially when emotions are involved. The details can get blurred very quickly.
Universal, most likely, has been gathering hard evidence this entire time. There’s no hiding from this, so you might as well find out as much as you can before you start making full statements to the public.
I saw the press conference with the family’s lawyer and my interpretation was that it was meant to influence the public’s perception. The lawyer was doing lawyer things, which also felt like speculation to me.
Regardless of the outcome, my prediction is that Universal’s rides will end up with more safety restrictions and become less “inclusive” to guests.
