I think you misunderstood my comment (which was essentially "good thing the police decided to commit clear misconduct by signing an NDA and then committing brady violations") But in any case, the justice system didn't work this way for a long time, and was effective. The exclusionary rule only came into play in 1914 in any real way. It also doesn't work this way in other countries and is effective there too. The cops, in the end, aren't punished because someone went free. We are. I'd posit that large amounts of civil liability for the cops who do this would be a much better deterrent than letting a criminal that isn't them, go free. (the other option, of criminally charging cops, is just never going to happen)
