A demonstration against police brutality on Saturday saw hundreds of Occupy Wall Street protesters and civil liberties activists join forces for a march through Lower Manhattan. At right, the marchers rallied outside New York City Housing Authority developments on Avenue D, accompanied by a strong police presence that kept an eye on them. Below, East Village activists John Penley, left, and Paul Shay listened in Union Square as people spoke out against police violence. Shay was injured last July and his wife, Monica, was killed along with three others, when they were shot by a former associate of Paul’s at their Pennsylvania home. “The outpouring of support from the neighborhood and political scene was overwhelming,” Shay said before the march’s start. “You go through life trying to do the right thing.” The Shays, longtime E. 10th St. residents, marched and spoke out against police brutality, especially in the 1980s.
