Posters that read "You cannot co-opt the movement against state violence to memorialize its perpetrators #blacklivesmatter" were posted over the center board in Collis Center. The left board, reserved by the College Republicans, has copies of the group's letter to College President Phil Hanlon and the Board of Trustees posted to it. Yesterday, the College Republicans Blue Lives Matter display on the reserved board was removed and replaced with Black Lives Matter posters currently on the adjacent board.
