Marquette University officials acknowledged Wednesday that the university made mistakes in how it handled student reports of sexual assaults and said they?ve worked out a way to improve how they report sexual assaults to city police. Previously, officials with Marquette?s public safety department left it up to the student who reported a sexual assault whether to report that assault to the Milwaukee Police Department. But that was against Wisconsin law, which mandates that a private security firm that believes a crime has been committed has to promptly notify police. Now students will be told the incident will be reported, but they have a choice of whether to talk to police.
