As Virginia State Police, elected officials and many others try to understand how a University of Virginia student wound up on a Charlottesville sidewalk, bloody and prone, one piece of the puzzle is conspicuously absent: body-camera footage. The Department of Alcoholic Beverage Control officers who arrested Martese Johnson outside a bar early Wednesday were not outfitted with such cameras, even though ABC pledged more than a year ago to put them on every agent. “Agents will be issued point-of-view cameras to be worn during operations,” ABC announced in November 2013, months after another controversial arrest.
