Watch: A march and prayer for Trayvon Martin

The United Black Christian Clergy, a ministerial alliance of more than 30 pastors throughout King County, led a peaceful prayer and march through Seattle's Central District Wednesday evening. The opening prayer was given by Rev. Dr. Samuel McKinney of Mount Zion Baptist Church.

The group is calling for the Justice Department to investigate George Zimmerman for civil rights violations against Trayvon Martin, and for the revision or removal of "Stop and Frisk" as well as "Stand Your Ground" laws.
