“I wonder if Mueller had the job to find the murderer of Seth Rich, would he still be looking?”
Probably. Since Mueller still doesn’t know who sent the anthrax in the 2001 attacks.
FBI/Mueller declared Bruce Ivins guilty after they drove him to suicide in 2008.
The NAS review in 2011 showed that was almost certainly not the case.
The best prediction of how someone will behave in the future is what they have done in the past.
If one wants to learn about Mueller’s deficiencies as an investigator, just look at the anthrax attacks investigation.
My hope is that eventually mueller will be exiled.
