According to a statement from the university, officials decided to cancel the lecture after about 30 minutes of shouting and protest from the audience, which included both students and community members (the lecture was open to the public). Brown University President Christina H. Paxson wasn't too happy about the message sent by the cancellation: "The conduct of disruptive members of the audience is indefensible and an affront both to civil democratic society and to the University’s core values of dialog and the free exchange of views," she said.

Here's some context for why some students wouldn't want Kelly speaking at their university: earlier this year, a federal judge declared that Kelly's signature "stop-and-frisk" policy was unconstitutional, violating both the fourth and 14th amendments — a charge long-lobbied by critics at the practice. The city is appealing that decision, but it's not the only Kelly-era NYPD policy facing current scrutiny. Under Kelly's watch, the NYPD secretly infiltrated and collected intelligence on the city's Muslim community. That program was documented by a Pulitzer-winning series of reports from the AP. According to the AP, that program never led to a terrorism lead, despite its justification as a counterterrorism tactic. Communities United for Police Reform, a group critical of Kelly's stop-and-frisk policy, issued a statement to the New York Times arguing that his reception at Brown shouldn't really surprise anyone: "it’s not shocking that after directing policing that violates New Yorkers’ civil rights and the U.S. Constitution without any remorse," the statement reads, "That Commissioner Kelly would be poorly received.”

Later on Tuesday, Brown University president Christina H. Paxson sent a letter to the entire Brown community concerning the cancelled speech. "This is a sad day for the Brown community," she writes. She adds:

I appreciate that some members of our community objected to the views of our invited speaker. However, our University is – above all else – about the free exchange of ideas. Nothing is more antithetical to that value than preventing someone from speaking and other members of the community from hearing that speech and challenging it vigorously in a robust yet civil manner.

The whole letter is now available on Brown's Facebook page.
