( CNN ) -- Screams of outrage . Crowds marching down streets , blocking intersections and interstates . Fists raised in silence . As the Ferguson grand jury 's decision was announced Monday night , protesters around the country -- who had begun to gather hours earlier -- responded in solidarity . In New York , a roving crowd wound its way through the city , surging to more than 1,000 in Times Square before heading toward the Upper West Side , CNN 's Miguel Marquez tweeted . Earlier in the evening , about 200 people flocked to Union Square , brandishing signs that read , `` Jail killer cops , '' and a large display , in lights : `` Black lives matter . '' Protesters knocked down barricades and headed toward the West Village before turning north , accompanied by police . Emotions boiled over in Philadelphia , too . ' A thousand Fergusons across America ' `` Shouts of `` f -- - the police '' at word of no indictment , '' a Philadelphia Inquirer reporter tweeted . `` A man with the mic : 'we do n't need to get mad . ' Others : 'yes we do ! ' '' In Oakland , California , shop owners posted signs in their windows , `` We support Michael Brown , '' as marchers took to the streets . A crowd filled the intersection at 14th and Broadway , and some demonstrators laid their bodies down in chalk outlines , reports on social media showed . Later they merged onto Interstate 580 , shutting down traffic . Similar scenes of a `` die-in '' were staged in downtown Seattle . `` Same story every time , being black is not a crime , '' protesters shouted , according to a report from CNN affiliate KIRO . In Washington , D.C. , a large crowd assembled outside the White House , with some protesters lying down on Pennsylvania Avenue . In Los Angeles , a city still scarred by the riots of 1992 , silent protesters staged a similar demonstration at the intersection of La Brea and Wilshire . A group also assembled in front of the Colorado Capitol in Denver calling for nonviolence , according to CNN affliate KMGH . The Chicago Tribune reported that some 200 protesters gathered outside the city 's police headquarters , chanting `` We are Mike Brown ! '' and `` I am Mike Brown ! '' They also carried signs , the paper reported , bearing phrases like `` Wo n't stop 'til we get justice , '' `` Killer pigs must pay , '' and `` Stop the racist killer cops . '' Later they marched through downtown before stopping at the State of Illinois Center , where they chanted into bullhorns . Chicago police scrambled to keep up . Protests around the country appeared to be largely peaceful , compared to the scenes unfolding in Ferguson . There , demonstrators set police vehicles ablaze and officers fired canisters into the crowds . In Atlanta , birthplace of the Rev . Martin Luther King Jr. , the streets appeared largely quiet . But at Morehouse College , where about 200 students gathered to hear the grand jury 's decision , a collective gasp rippled through the crowd . What 's next for the Michael Brown family ? Some of the students at the historically black men 's school looked at one another in disbelief , others started to tear up , and a few stared ahead as their jaws dropped . Police sirens wailed in the distance as the students chanted : `` Ferguson 's hell is America 's hell . '' Kevin Harvey , a senior dressed in a blue blazer , button-down shirt and penny loafers , walked away from the demonstration with his head down . He said he was angry and bewildered by a storyline that 's become all too familiar . `` I 'm afraid to raise my son in this country , '' he said . `` When I do have a family , I 'm afraid to raise him in this country and that 's a terrible thought . Because I know that he is not valued . '' Complete coverage of what 's happening in Ferguson . When asked his reaction to the verdict , Harvey tried to sort through his emotions . `` Confusion , anger , and generally just being upset , '' he said . `` I 'm scared and frustrated . '' Long before the grand jury decision was shared , announcing that Officer Darren Wilson would not be indicted for the murder of 18-year-old Michael Brown , the nation held its collective breath . As the sun set back East , people rose up -- hours before the decision was announced after 9 p.m. EST .
