A high school basketball tournament on the Northern California coast has become the latest flashpoint in the ongoing protests over police killings of unarmed black men after a school was disinvited because of concerns its players would wear T-shirts printed with the words 'I Can't Breathe' during warmups. The athletic director for Mendocino High School was informed by his counterpart at Fort Bragg High School this week that neither the boys nor girls teams would be allowed to participate in the three-day tournament hosted by Fort Bragg High starting Monday, Mendocino Unified School District Superintendent Jason Morse said.
