They don't like reporting crimes because it's bad PR. You have to rely on the students to report it and let the newspapers know.
It is not just the college that is at fault. The town/county/city police and District Attorney do not take an active role in investigating or prosecuting perpetrators of sexual assault even when they are reported and identified. The schools don't want to "tarnish" their reputation by reporting attacks/incidents and "law enforcement" as part of the money making machine in most districts, may take a cursory look at reports but only with an eye on how to dispose of an embarrassing incident for a major town employer. The concern is more for dollars than for student and community safety. The "punishment" dealt to the assailant of my daughter was : write a 500 word essay on why drinking is bad. The police/DA did nothing and with no criminal charges, the school did not "have to" report the incident.
As a victim of an assault on a SUNY campus in the early 1980's, I've always advocated for making our college campus's safer for our students. Officials at the school I attended were more worried about a lawsuit than for my well being. Full disclosure of sexual assaults on their campus may finally force the schools to address the problem that exists and establish effective programs that support and protect their students.
