lt. In a letter sent Friday to students responding to their concerns about Boston University’s policies and actions around sexual assault accusations, Jean Morrison, BU provost and chief academic officer, outlined a series of new commitments BU is making to help prevent sexual assaults from happening on campus and to improve policies around reporting and investigating processes for assaults. “Boston University should be a place where all feel safe and welcome, and we are committed to doing the work to achieve this goal,” Morrison writes. “While we will continue to discuss opportunities for improvement, I am hopeful that these initial commitments will be meaningful steps in the right direction in ensuring a safe and healthy environment for all members of our community.”
