A trooper knew he was holding an incorrect charge against my wife. The charge carried with it pretrial restrictions that would not have occurred under the correct charge (a "leash law" violation). IAD didn't care. The investigation even tried to explain the trooper's lie to the judge about why he was amending the charge as just a misunderstanding... yeah, ok. Neither state reps replied to my two letters. The governor claims he can't get involved in a court issue even though I only wrote him about the practices of the state police (which he oversees) leading to violations, and that the policy should change. I contacted the ACLU, but this is not a big enough issue for them.
The only thing with any traction is an investigative journalist who is pitching the story to their editor.
I'm not holding my breath, but I am either in the process of submitting or waiting to hear about: a complaint to the Bar about the ADA having information that it was an incorrect charge and allowing it to stand, the DOJ to investigate the practices of the state police knowingly holding false charges, and a response from my latest letter to the governor.
I would guess that would be the most expedient route, if you can get them interested. If you work for a big employer in their district, and are comfortable with it, having your employer reach out to them might help.
Well, the first more than the second; a rep doesn’t have to read your letter to be briefed and direct staff followup, which may itself produce results.
If it's a form letter, you're just going to be lumped in with the others of similar concerns.
In the case of the FBI, the FBI Office of Professional Responsibility (essentially, the FBI’s “Internal Affairs” unit), DoJ Inspector General, your reps in either House of Congress, or members of the Judiciary Committee (in either House) or the Permanent Subcommittee on Investigations (in the Senate) or the Oversight and Reform Committee (in the House).
May also be worth going to media and/or NGOs, though which, if any (especially of the latter) are most likely to be useful varies a lot by who you are and what the exact details of thr misconduct are.
Private litigation may or may not be useful (both governmental and personal immunities come into play) and can be very expensive (though NGOs may help with this.)
