Protests spread across the United States late Monday over the explosive grand jury decision in Missouri against indicting a white cop who shot dead an unarmed black teen

Protests spread across the United States late Monday over the explosive grand jury decision in Missouri against indicting a white cop who shot dead an unarmed black teen.
  
Angry people took to the streets from Seattle out west to Chicago in the middle and New York, the nation's largest city, as the hotspot town of Ferguson, Missouri -- where the decision was rendered -- roiled with rioting.
  
Not long after President Barack Obama appealed for calm over the hotly awaited ruling in Missouri in the case of slain teen Michael Brown by white policeman Darren Wilson, several hundred people gathered in front of the White House.
  
They chanted slogans such as "Hands up, don't shoot" and waved banners saying "stop racist police terror" and "Justice for Mike Brown."
  
That demonstration was peaceful. The rally outside the White House dispersed after midnight but demonstrators headed elsewhere, possibly toward the US Capitol, the seat of Congress, AFP correspondents observed.
  
In New York City's Times Square, several hundred people rallied carrying banners protesting "police tyranny." Others had slogans saying "racism kills" and "no justice, no peace."
 
The police presence in New York City was heavy. A helicopter flew overhead. Another rally was held in the city's Union Square.
