In 1871, American lawyer Clement Wallandigham filed a case defending a man accused of murder due to a quarrel in a bar. He built proof of innocence on the fact that the victim accidentally shot himself, pulling a gun out of his pocket in an uncomfortable position. Wallandigham wanted to demonstrate this development by putting another gun in his pocket (as he thought uncharged). As a result, the lawyer, taking him out, shot himself. He died of his wounds and his defendant was acquitted.
