People of Illinois v Armstrong

Before he went into politics, Abraham Lincoln was a lawyer. In one of the most famous cases he took, he defended family friend William "Duff" Armstrong against a murder charge by pointing out that the weather in head witness Charles Allen's testimony didn't match up with records. While Allen isn't the one who did it, his credibility as a witness was shattered, and the case was over.
