A video that captured the brutal arrest of a Black college student pulled from his car and beaten by officers in Florida has led to an investigation and calls for motorists to consider protecting themselves by placing a camera inside their vehicles. William McNeil Jr. captured his February traffic stop on his cellphone camera, which was mounted above his dashboard. It offered a unique view, providing the only clear footage of the violence by officers, including punches to his head that can't clearly be seen in officer body camera footage released by the Jacksonville Sheriff's Office.
