The problem here is that the nominal lead agency is and will remain PCSO.
That doesn't mean they're the ones actually running the show.
So, what you appear to have here is a titular head (PCSO), and a different actual true lead (FBI).
There is such a thing as too many cooks in the kitchen sometimes.
PCSO made some horrific blunders right out of the gate.
It looks as if the SO has been regulated to providing security/traffic detail from the outside looking in.
It appears as if the FBI is doing the lion's share of the real investigative work.
The PCSO appears to be incapable of handling this type of investigation, yet it's their investigation.
The FBI can't wrest it from them.
Consequently, here we are.
I'm sure a lot of us have worked with and/or for a Nanos type at some point.
Let's all spare a thought for the FBI agents who are trying to work in concert with Sheriff Nanos whilst also trying to keep him from complicating their work with his open-mouth-insert-foot routine.
