People v. Fisher. Mr. Fisher crushed his fiancé's head with a hammer. Five people saw him do it, he was covered in blood and brain matter... he was acquitted. It wasn't my first case, or my tenth. It happened four years ago. No such thing as a slam dunk.
You went to bat for a woman who shot her husband in cold blood, and who would have killed anybody else she found in his office. If I had to betray a confidence to ensure that she goes to jail, so be it. These are the rules we live by.
