You have far more faith in the system than I do and especially that the police wouldn't deny the existence of evidence that you said what you say you said if it suited them. Things are conveniently lost, misfiled or "never existed" in the first place.. They withold your statement from discovery. You claim they have a written report of your statement and knowingly withheld it. They claim they don't have it, have never had one, and it's nowhere to be found. Now what?
