Starbucks will be closing all of its U.S. stores - more than 8,000 - for the afternoon to conduct racial-bias education training for employees. The decision comes after two black men were arrested at a Philadelphia location for trespassing. Now, a video of a second incident, this time at a Los Angeles location, is reigniting calls for a boycott of the coffee chain.
