I have, Except for the hundreds part. On one MVA, our defendant was prosecuted by a District attorney who withheld evidence, and by investigating police who sat on an eyewitness's testimony. The testimony was explicitly exculpatory, and when another investigator discovered it, the case was dropped.
This case in France is one of manslaughter. I have seen principals in manslaughter cases violate law. The defendant in the case I describe was looking at fifteen years in prison....yet the "authorities" wanted a conviction, at any cost. Don't lecture me....
