In 1871 while representing a defendant in a murder case lawyer Clement Vallandigham a United States Congressman and one time political opponent of Abraham Lincoln wanted to prove the supposed murder weapon could have accidentally been fired by the victim. Taking the gun from evidence Vallandigham tried to demonstrate to the jury how the victim might have shot himself. His mistake was in not checking to see if the gun was loaded. Just as Vallandigham had speculated the firearm discharged and just as he’d conjectured the result was a mortal wound. On an upbeat note at least the defendant was acquitted.
