The fact is, the FBI has a long history of incompetence and worse: falsifying evidence; framing innocent people (go here, here, here, here, here, and here); and even shooting people for what appears to be no justifiable reason. With the shootings, the Bureau “reviews” the situation, then, it almost always absolves itself.
When its employees try to work within the system to improve it, quietly blowing an internal whistle, they are subjected to severe retaliation.
For more on the range of problems at the Bureau, see the links and summaries below: a small selection of our FBI stories that demonstrate the consequences of those bad choices. They have endangered national security, harmed our civil liberties, harmed innocent people, and appear to have put out false narratives, misleading the government, the media, and the public.
