Jury selection has begun in two high-profile murder trials of white police officers who killed unarmed black men. In Ohio, former University of Cincinnati police officer Ray Tensing shot and killed 43-year-old Sam DuBose last year after stopping him for not having a front license plate. In North Charleston, South Carolina, officer Michael Slager faces a murder charge after a bystander filmed Slager shooting 50-year-old Walter Scott in the back as he ran away.
