State of emergency called in Ferguson after gunfire mars protests

Protesters, some carrying placards, assembled on a street near the site where Michael Brown, a black teenager, was shot dead by white officer Darren Wilson a year ago and ignited a national firestorm on race relations.

The emergency order was issued for the St. Louis suburb and surrounding areas amid tensions between residents and police after officers shot and critically wounded an 18-year-old man in an exchange of gunfire Sunday night that marred what had been a day of peaceful demonstrations.

Prosecutors charged the man, Tyrone Harris, who was in critical condition in a hospital, with four counts of assault on law enforcement, five counts of armed criminal action, and one count of shooting a firearm at a vehicle. His bond was set at $250,000.

St. Louis County Executive Steve Stenger said he made the state of emergency declaration because of "the potential for harm to persons and property".

In Ferguson, a few merchants said they were ready to protect their businesses with firearms, while store owners pleaded for calm.

Dellena Jones, an owner of a Ferguson hair salon vandalized on Sunday night, boarded up a smashed window and had a sign displayed in a window still intact that read: "We Must Stop Killing Each Other."

On a day of civil disobedience called by activists to protest the shooting of Brown and other unarmed black men across the United States by police, 57 people were arrested as they broke through barricades at a courthouse in St. Louis and blocked the entrance, the U.S. Attorney's Office for the Eastern District of Missouri said.

Among those arrested was Princeton University professor and activist Cornel West, according to a protest organizer.

On Monday afternoon, dozens of protesters were arrested after blocking rush-hour traffic on Interstate 70 a few miles (km) from Ferguson, according to a Reuters witness.

The protesters could be seen sitting or kneeling with their hands secured behind their backs, flanked by police officers and vans with doors ajar.

Clergy and civil rights groups led a rally of more than 100 people through city streets, shouting, "This is what democracy looks like" and "Black lives matter".

The death of Brown and a grand jury's decision to spare the white officer from criminal charges led to a wave of demonstrations that boiled over into rioting and arson at times and spawned sympathy rallies across the country.

Brown's death also prompted greater scrutiny of racial bias within the U.S. criminal justice system, giving rise to the "Black Lives Matter" movement that gained momentum from other high-profile killings of unarmed minorities by white police in cities such as New York, Baltimore, Los Angeles, Cincinnati and most recently Arlington, Texas..

NIGHT OF VIOLENCE

What began as peaceful demonstrations on Sunday night in Ferguson descended into chaos as volleys of gunshots rang out as police in riot gear tried to disperse protesters blocking traffic and smashing storefront windows along a street that was a flashpoint of riots last year after Brown, 18, was shot dead.

Missouri Governor Jay Nixon called Sunday's violence "a sad turn of events" carried out by a criminal element and appealed for peaceful rallies on Monday. But Nixon, who had deployed the National Guard to quell violence last year, did not make any mention of additional security for those rallies.

The county's order allows it to distribute money and material for emergency purposes "and to protect the health and safety of residents." It also allows police to perform "all duties necessary with respect to preservation of order".

Police said Sunday's gunfire began with two groups of agitators apparently shooting at each other before one gunman darted across a parking lot and was confronted by four officers who pulled up in an unmarked vehicle.

Police said that the suspect, Harris, then opened fire on the police vehicle and was badly wounded in the ensuing foot chase and exchange of gunshots with the four detectives.

The shooters "were criminals; they weren't protesters," St. Louis County Police Chief Jon Belmar said, estimating that 40 rounds had been fired in the exchange. "We can't sustain this as a community," adding, "It's untenable at this point".

Harris's father said his son did not have a gun.

"He was running for his ... life because someone was shooting at him," Tyrone Harris, Sr., said in a telephone interview from his St. Louis-area home.

The younger Harris was out on bail awaiting trial on charges of stealing a motor vehicle, theft of a firearm and resisting arrest. He was charged with those crimes on Nov. 5, 2014, and released after posting a $30,000 bond on Dec. 19, records showed.

According to a police officer's statement in the charging document, on Nov. 4 Harris sped away from detectives in a stolen Dodge Intrepid, until he ran into spike strips that police had set up to stop him. After he finally came to a stop, he removed a handgun from his waistband and placed it between the seat and the console.
