No good deed goes unpunished, and you can't even sue for it.
That's a summary of the Seventh Circuit Court of Appeals' decision in Katz-Crank v. Haskett, which says an acquitted lawyer is barred from suing government officials who unsuccessfully prosecuted her. Here's what happened:
An attorney discovered her client was committing fraud and reported him to authorities. But they already knew about it and were investigating whether the attorney was involved. They charged her with aiding and abetting, and she was acquitted. She sued, and a judge dismissed. The court of appeals affirmed.
