The FBI did NOT
Use subpoenas to interview
*State Dept employees
*Those who set up private server
*Those with knowledge of emails
So none of them were under oath or had the testimony recorded.
The FBI did NOT DO
*Search warrants for Mills, Samuelson laptops
*Emails were secured thru consent agreements
Even lead investigator Peter Strzok was pushing to use more aggressive measures.
The FBI did NOT
*Obtain personal devices of Clinton's top aides
*They sometimes used private email, devices for State dept work
But the OIG determined those are judgement calls that are within the discretion of the FBI agents to make. https://conservativedailypost.com/unsealed-records-confirm-special-treatment-for-hillary/
