John McAfee: The FBI Is Either Incompetent or Corrupt, Here's the Truth.

If you read into why the recent case against Hillary was reopened, one big reason was because field agents were resigning and there was practically a mutiny inside the FBI.

I think it's unfair to say "the FBI" is corrupt, because there were a number of agents who did honest and diligent work to ensure the case was investigated properly. There is/was a significant number of very skilled agents working the case who were/are blocked by people way above their pay grade from performing a proper investigation.

Those people need to be held responsible personally, and the FBI needs to perform a proper investigation without being told to halt their investigation by bureaucrats in the department of justice.
