At one time, I would have trusted the FBI almost totally.
Ruby Ridge was the first time I knew they were rotten on the inside. The two supervisors whose names I no longer remember, had violated FBI rules and probably the law.
After all had finally settled, they were both given official reprimands in their personnel files. Having worked for civil service for many years, I thought that was the end of their careers. Most people who get one simply resign as it means their careers are basically over.
Imagine the surprise when they were both promoted just weeks later. A totally corrupt organization.
