Alcoholic Beveridge Control (ABC)RICHMOND, Va. (AP) _ Virginia Gov. Terry McAuliffe is ordering Alcoholic Beverage Control agents to be retrained following a high-profile arrest that left a University of Virginia student bloodied and shouting allegations of racism.   McAuliffe signed an executive order Wednesday ordering ABC agents to undergo retraining on the use of force, cultural diversity, community policing and interaction with youth. The governor had previously ordered the state police to investigate the March 18 arrest of Martese Johnson. The 20-year-old’s arrest by ABC agents outside a Charlottesville bar comes two years after another U.Va. student was arrested by agents who mistook a carton of sparkling water for beer. The incident sparked a public backlash, and the traumatized student later settled a lawsuit for $212,500.
