It’s hard to believe, and even harder to believe that anyone so bold as to kill someone like this is also incredibly stupid.
In other words, the dark state powers-that-be can easily find this attending surgeon, if he exists.
If I was one the dark state powers that took out Rich, I’d find the people from the hospital that night and “ensure” no one posted another thread on Reddit or anywhere.
It would be an EXTREMELY loose thread to just leave hanging for Mueller to pull on.
Why risk THAT?
Nope. The tales from movies is too often just that. Tales— meaning Fiction.
Problem is they will have to take out the entire staff since all the staff will be well aware by now of the problems that happened with Rich. That doesn’t mean they won’t take out the entire staff, not above the capabilities of the regime especially with no law enforcement there to stop them.
