Participants with One Million Moms for Gun Control, a gun control group formed in the wake of last month's massacre at a Newtown, Connecticut elementary school, holds a rally and march across the Brooklyn Bridge on January 21, 2013 in New York City. The group marched to City Hall where they held a rally and demanded stricter measures against guns. One Million Moms for Gun Control said the event is inspired by the Rev. Martin Luther King Jr.'s message of nonviolence.
