Something I hear over and over from educational security folks is that their working relationship with law enforcement is critical to campus security. Many schools have memorandum of understanding documents with their local police department, establishing an official relationship and setting guidelines about each department's role.
I've been periodically reading about the murder of Yeardley Love, a University of Virginia student who was allegedly killed by an ex-boyfriend. While this is certainly tragic, it's the type of incident that likely could not have been stopped by campus security, especially if there were no previous incidents.
However, something that jumped out at me in this USA Today article was that the suspect, George Huguely, was previously arrested for resisting arrest and public intoxication in Lexington, Va. in 2008. Huguely, according to the arresting officer, cursed and made threats and had to be subdued with a stun gun, according to the article.
However, the university was unaware of Huguely's previous arrest. The president of the school, John Casteen, said the law did not require police departments to inform schools about such arrests, though he said some departments do so as a courtesy. In addition, Virginia students are required to self-report such arrests, but of course Huguely did not.
While I'm not sure that it's necessary to make it a law, I would bet that most security directors at major universities do expect police to contact them of incidents involving their students. In this case, Lexington is about 70 miles away from the university and I would assume that police and university officials probably didn't have an established relationship. But does this type of incident demonstrate the need for police to always contact the university when any student is arrested? I'm sure there's logistical issues there (and the police probably want one more rule to follow), but perhaps it could've brought to light a troubled student. More information is always better than less, right?
