Protesters prepare for justice march in capital

Thousands are expected to descend on the nation's capital Saturday for a rally against police-involved deaths of black citizens.
The family of Akai Gurley will be attending the rally. Gurley, of Brooklyn, was unarmed when a rookie NYPD officer shot and killed him last month in the stairway of a public-housing complex.
The National Action Network, led by the Rev. Al Sharpton, is among the groups leading the planned protest in Washington this Saturday.
The Rev. Kevin McCall, of the National Action Network, will also attend the event. "Justice in all lives matter," says McCall. "Black lives matter here in New York City."
Organizers say that they aren't against police, but they are against police brutality.
Relatives of Eric Garner, a Staten Island man who died after being placed in a chokehold by a police officer; Michael Brown, who was shot and killed by a police officer in Missouri; Tamir Rice, a 12-year-old who was fatally shot by Cleveland police who mistook his air gun for a real weapon; and Trayvon Martin, who was killed by neighborhood watch member George Zimmerman, plan to attend the march.
Participants of the "Justice for All March" plan to gather at 10:30 a.m. at Freedom Plaza. The march is scheduled to start at noon.
For people who can't attend the march in Washington, a march is also planned in Washington Square in Manhattan.
