A man has sued a police officer, alleging that the officer violated the man's civil rights by using excessive force while arresting him. At trial, the officer admits having hit the man in the head with the butt of his gun, but contends that the force was necessary, because the man was resisting arrest. In support of his contention, the officer seeks to introduce evidence that the man had resisted arrest on three prior occasions during the last 10 years.Is this testimony regarding the man’s conduct during the three prior arrestsadmissible?
