A relative of mine once overheard a police sergeant rehearse the "story" he planned on telling the judge with his subordinate officers. He told his defense attorney, who basically shot holes through any credibility the cops may have had, and prevented the prosecutor from making anything stick, even when he tried demoting the charges from felony weapons to "disturbing the peace" -- charges my relative was innocent of regardless. I believe the police sergeant was fired, but he was not prosecuted.

In case you're wondering, me and mine are some of the whitest people you'll meet. It happens to black people more, but it can happen to anyone.
