The problem is that you cannot expect an organization to effectively police itself. That's just a simple fact of life. Organizations will protect their own and refuse to admit wrongdoing until they are forced to by outside means. This is human nature. Prosecutors can't prosecute cops because they are part of the same system. The only way you hold the justice system accountable for miscarriage of justice is to have a completely separate body act as the check.

Might as well extend that to the other branches as well. Create a 4th branch of government who's only purpose and power is to jail members of the other branches who break the law since they can't be expected to police themselves and power corrupts all.

Kind of like how members of the military are subject to UCMJ courts. Civilian members of government should be subject to a court as well.
