More than 30 people walked out of the Barton Community College Board of Trustees meeting, minutes after the meeting began Thursday afternoon. They had come to the meeting for one purpose: to express their dismay with last week’s firing of head cheerleading coach Debbie Warren, who had been at the college for 27 years. Board chairman Dr. Paul Maneth said student Luke O’Bryan had approached him about supporters speaking at the meeting, and the students had agreed to have one spokesman who would be given five minutes at the beginning of the meeting.
