The protests haven't stopped.

From Berkeley to basketball courts and now on Capitol Hill, the demonstrations over recent grand jury non-indictments have stretched beyond what most people expected.

The protests on the Hill, as first reported by Tim Mak at The Daily Beast, included about 150 staffers as well as Rep. Elijah Cummings (D-Md.):

Senate Chaplain Dr. Barry Black led the crowd in prayer, accompanied by dozens of Congressional staff and members of Congress, including civil-rights leader Rep. John Lewis. They were gathered there, Black said, to be a "voice for the voiceless."

"Forgive us when we have failed to lift our voices for those who could not speak or breathe themselves," Black prayed, making an unmistakeable reference to the case of (Eric) Garner, whose cries of, "I can't breathe!" became an animating impetus for protesters.

In 2012, staffers staged a "Hoodies on the Hill" protest to bring attention to the death of Trayvon Martin.
