Person I was representing was on trial for Assault in the Third Degree and DUI. In my state, A3 means you've assaulted an aid worker or police officer and is a felony. The allegations are that he was very verbally abusive to the officers and, at one point, kicked one in the face.
We're sitting at the defendant's table and the officer is testifying about the statements my guy made to him, including some pretty horrific name calling. Out of nowhere, my client screams "You're a fucking liar! Fuck you, you son of a bitch!!!"
We lost that trial.
Another time, the judge asked a client whether anyone had coerced him into pleading guilty, and he said "Yeah, my attorney." I about shit my pants, but he laughed and said, "I'm joking. No."
