Cities across the nation are gearing up for marches celebrating the life of Dr. Martin Luther King, while drawing attention to police violence directed at communities of color.

The cases of Trayvon Martin, Michael Brown, Eric Garner and the "Black Lives Matter Movement" have become national symbols of a conversation about police brutality and racial injustice.

A group in Minnesota involved in the non-violent protest that partially shut down the Mall of America last month says it's planning a march on Monday to reclaim the legacy of Martin Luther King Jr.

In New York City, many are preparing for numerous protests and panels planned over the next several days.

New Yorkers are eager to see how Mayor Bill de Blasio commemorates the holiday and what he might say about racial inequality and criminal justice.

Protesters in Boston have begun blocking traffic and train service in and around the area that could make things interesting for those trying to get to Gillette Stadium in Foxboro for Sunday's Colts-Patriots AFC title game.

Marches and demonstrations are also planned on the Martin Luther King holiday in Chicago, Seattle, Philadelphia, California, Georgia, Alabama, and New Jersey.
