Myron Pitts, who covered the Hennis trial for the Fayetteville Observer, has this article summing up the evidence. The whole story is worth a read, but my favorite line is this:
Hennis' lawyer, Frank Spinner, said at the bottom of the courthouse steps that the jury never got to know his client, who did not testify. The jurors instead were treated to gruesome photos of the murder scene, he said.Um, excuse me, Mr. Spinner, but whose choice was it not to testify? At common law, the defendant wasn't allowed to testify, but we got rid of that rule a long, long time ago.
