Rutgers University students wore black on Friday to remember a classmate who committed suicide as a lawmaker proposed stiffer penalties for invasion of privacy — the charge against the roommate accused of secretly streaming video of the victim's sexual tryst with a man.

Middlesex County Prosecutor Bruce J. Kaplan said Thursday that more charges were possible under New Jersey's hate-crimes law.

"We will be making every effort to assess whether bias played a role in the incident, and, if so, we will bring appropriate charges," he said in a statement.

The legal question has to do with the motive. People can be found guilty of a bias crime in New Jersey if a jury agrees they committed a crime because of a belief that the victim is a member of a protected group, such as a racial minority or gays and lesbians.
