Sen. Marco Rubio doesn’t have much time for Democrats. But he does have two daughters.And so it was that Wednesday morning he found himself standing in solidarity with a bipartisan group of senators that included Democrats Kirsten Gillibrand and Claire McCaskill as they announced legislation to curb sexual assault on U.S. campuses.The proposed Campus Safety and Accountability Act addresses the non-reporting, under-reporting and non-compliance with the previously passed Clery Act, which requires schools to report crimes on and off campus.With about a dozen designated staff at the Department of Education to oversee reporting at more than 6,000 colleges and universities, it’s no wonder 63 percent of schools fail to comply. They have an enormous public relations incentive not to: Would any responsible parent send their daughter to a college whose stats showed she would have a good chance of being sexually assaulted sometime during her four years there?The new legislation would correct lax oversight, enforcement, training and staffing at the Department of Education. It increases penalties for failure to report violations to as much as $150,000 per violation, up from $35,000. Schools would have to administer an anonymous survey on assaults that would be published annually. They will also have to keep a searchable database on pending and resolved complaints that would give parents a way to judge the safety of campuses.A 2000 Justice Department report estimated that less than 5 percent of college rape victims report their attack. A Senate investigation set up to guide the legislation found that more than 40 percent of U.S colleges and universities haven’t conducted a single sexual assault investigation in the past five years. Another 20 percent don’t investigate all the incidents they’ve reported to the Department of Education. About 19 percent of undergraduate women have been the victims of sexual assault. Nor are schools equipped to deal with violent crime. They’re not law-enforcement agencies, and the systems set up to adjudicate complaints make kangaroo courts look good.One of the most depressing findings from the survey, which included 49 of the 50 largest public universities, was that what we suspected — sports stars get special treatment — is actual policy. Parents should get a list of the 22 percent of schools where a sexual assault accusation against a quarterback is handled not by a dean but by the athletic department. Under the new bill, schools can no longer allow athletic departments or any other subgroup to handle such complaints.Schools would be required to use a uniform process for campus disciplinary proceedings, rely on trained adjudicators and provide training for staff and faculty (one-fifth of schools don’t have any such personnel). A victim couldn’t be penalized for an ancillary offense such as drinking, or for coming forward, and would be assigned a trained confidential adviser to see him or her through the proceedings.Despite its bipartisan credentials and urgency, the law’s chances of passage aren’t good in a gridlocked Capitol. But there’s hope. Republicans and Democrats alike may have daughters. Margaret Carlson is a Bloomberg View columnist.
