PROVIDENCE, R.I. (AP) — New York's police commissioner is set to deliver a lecture at Brown University on "proactive policing."

Raymond Kelly is expected to discuss his time as head of the New York Police Department and his efforts to drive down crime in a lecture called "Proactive Policing in America's Biggest City" on Tuesday afternoon.

Some students and social justice activists say they plan to protest before the lecture because of the department's stop-and-frisk policy and its surveillance of Muslims.

The department is fighting off lawsuits alleging it has engaged in racial profiling while fighting crime. Kelly and Mayor Mike Bloomberg have denied the accusations.

The lecture is sponsored by the Taubman Center for Public Policy and American Institutions. The students planning the protest had called for Brown to cancel it.
