This is Purely interpretation,
But I tried to read the initial, said screw it went straight to the Conclusion.
"First, we found that several FBI employees who played critical roles in the
investigation sent political messages—some of which related directly to the Midyear
investigation—that created the appearance of bias and thereby raised questions
about the objectivity and thoroughness of the Midyear investigation. "
Per the conclusion, There was Perceived Bias.
Secondly,
"then Director Comey chose to deviate from the
FBI’s and the Department’s established procedures and norms and instead engaged
in his own subjective, ad hoc decisionmaking. "
We knew this.....why as the Head of the FBI, deviate?
Third
" there was a troubling lack of any direct,
substantive communication between Comey and then Attorney General Lynch in
advance of both Comey’s July 5 press conference"
The Investigators, did NOT discuss with the Prosecutors? How does this WORK?
These are the conclusions points? Insubordination, didnt Yates get fired? So lets get over the firing.
Is this the last time a politically charged investigation and potential Bias? Nope but IG put recommendations and stated that existing policies should be followed.
THAT being said, It does NOT discuss, the effects and the re-investigation or reopening of the existing/closed cases/matters that had Potential EFFECTS of the above findings.
That is the more concerning, part. So I dont know how your title comes to say NO bias, when the IG reports that it shows seemingly bias??
