Eboni S. Cohen, a third-year student at Harvard Law School (HLS), said she fears for the life of her 13-year-old brother when she thinks about the outcome of New York's Amadou Diallo case.

Yesterday, she and other members of the Black Law Students Association (BLSA) began a poster campaign in Harkness Commons, showcasing stories of HLS students who have been affected by racial profiling and police harassment.

They want to make the community aware that the prejudices that they claim caused Diallo's death figure very personally into their lives.

"We want to make sure that people know that even we, as Harvard Law School students, aren't immune to this type of behavior from the police," said Nicole D. Lewis, a first-year HLS student who is spearheading the poster effort.

Diallo, a West African immigrant, was shot and killed by four white police officers in the lobby of his Bronx apartment after they mistook a wallet he held in the air for a gun. On Feb. 25, all four officers were acquitted of second-degree murder charges.

Jess E. Alderman, a third-year student at HLS, was walking through Harkness Commons last night when she noticed the banner that BLSA had posted on the wall. It read, "Once it was Diallo. Once it was me. Next time it could be you."

Displayed underneath is the story of Mari E. Zellner-Sawyer, Alderman's classmate, who claims her father has been a victim of racial profiling.

Zellner-Sawyer wrote in her testimony that when her white mother and black father took walks together through their northern California neighborhood, their white neighbors sometimes called the police to report suspicious activity or assault.
