NEW: Source: On Friday police plan to release name of officer who shot Michael Brown

Missouri's governor says state troopers will take over security in Ferguson

Captain says "we are going to have ... the approach that we're in this together"

Justice Department to help local authorities with crowd control, Holder says

Ferguson, Missouri CNN  — 

State troopers are taking over security in this St. Louis suburb after days of clashes between local police and protesters.

Gov. Jay Nixon said he decided to put the Missouri State Highway Patrol in charge of security because “at this particular point, the attitudes weren’t improving, and the blocks towards expression appeared to be a flashpoint.”

Lately, the community of Ferguson, which has been the scene of demonstrations and a strong police response in the wake of a weekend police shooting that left African-American teenager Michael Brown dead, has looked “more like a war zone, and it’s not acceptable,” Nixon said.

Now, authorities – who’ve faced accusations that they’ve used excessive force in response to demonstrations – will be taking a different tack in an effort to calm tensions, officials said Thursday.

“We’re all about making sure that we allow peaceful and appropriate protests, that we use force only when necessary, that we step back a little bit and let some of the energy be felt in this region, appropriately,” Nixon said

Chosen by the state’s governor to head up the new security operation, Missouri State Highway Patrol Capt. Ron Johnson said he planned to meet with protesters Thursday.

“We are going to have a different approach and have the approach that we’re in this together,” he said.

As groups of protesters grew Thursday night, the demonstrations were calm.

Some said they were prepared for police aggression, despite what authorities have promised.

“Gas me, shoot me, I will stand my ground,” one protester’s sign said.

But Antonio French, a St. Louis alderman who was arrested at a demonstration in Ferguson Wednesday, said he’s already noticed the new tone.

“Really, it has been the police presence, the heavy-handed presence, which has escalated the situation and I think led to the violence each night. And so it’s good to see this new approach,” he said. “Already there is a different attitude and a different interaction between the crowd and police, and I am very hopeful for a peaceful night.”

And protesters may be close to getting a response to one key demand.

On Friday, police in Ferguson plan to release the name of the officer who shot Brown, a source close to the investigation told CNN.

Police chief: City is a ‘powder keg’

Earlier Thursday, Ferguson’s police chief described the city as a “powder keg.”

“The whole situation is not good at this point,” Chief Thomas Jackson said a day after clashes in which police fired smoke bombs, tear gas and rubber pellets at protesters who he said had thrown firebombs at police and engaged in gunfire.

Jackson said police would talk about changing “not only the tactics but also the appearance” of law enforcement.

U.S. Justice Department officials have also offered to assist local authorities control crowds “without relying on unnecessarily extreme displays of force,” Attorney General Eric Holder said in a statement Thursday. The offer has been accepted, he said.

Jackson said protesters also have to do their share by remaining peaceful.

“We need everybody to tone it down,” he said.

Governor: ‘This has clearly touched a nerve’

Ferguson has been the scene of protests since Saturday, when a police officer shot and killed Brown, who was unarmed. Police say he was trying to grab the officer’s gun. Witnesses say the 18-year-old was holding his hands in the air when he was fatally shot.

And protests over the controversial case have extended beyond the St. Louis suburb. Demonstrators expressed solidarity with Brown and Ferguson’s protesters at so-called “day of rage” protests across the country on Thursday.

Protesters are angry that police have not released the name of the officer involved in the shooting, and they worry that a cover-up is in effect. St. Louis County police and federal investigators are looking into Brown’s death. No charges have been filed.

Although locals say race relations have long been troubled between the city’s mostly African-American population and the mostly white police force, anger spilled out after Brown’s death, resulting in protests, violence, looting and fires.

Brown’s death and demonstrations over the case have resonated far beyond that city, Nixon said Thursday.

“These are deep and existing problems not only in Missouri but in America, and this has clearly touched a nerve,” he said.

President Barack Obama spoke out on the situation Thursday, criticizing how some police responded.

“There is never an excuse for violence against police or for those who would use this tragedy as a cover for vandalism or looting,” he said. “There is also no excuse for police to use excessive force against peaceful protests or to throw protesters in jail for lawfully exercising their First Amendment rights.”

Their comments came after a night in which heavily armed police and protesters clashed, two reporters were briefly detained and an Al Jazeera America camera crew complained that police shot tear gas at them.

After ordering protesters and reporters to turn off their cameras, police fired smoke bombs, tear gas and rubber bullets at protesters after some threw objects at them Wednesday, according to media accounts. CNN crews have not been ordered to turn off their cameras during the protests.

Twelve people were arrested – including the two reporters, Jackson said. Two officers were injured, including one whose ankle was broken when a brick was thrown at him.

Cousin: ‘We’re still looking for answers

On Wednesday, the American Civil Liberties Union of Missouri filed a lawsuit seeking the release of the officer’s name under the state’s open records law.

It’s unclear whether the suit will succeed. Missouri law provides a specific exemption barring the release of records that authorities conclude are “likely to pose a clear and present danger” to victims, witnesses or others.

Officials say police officers, and others in the administration and police force, have been subjected to death threats.

Neil Bruntrager, general counsel for the St. Louis police officer’s association, said the name of the officer involved in the shooting should be withheld until an investigation is completed.

“The moment you put a police officer’s name out there, that police officer becomes a target,” he said.

On Thursday, the shadowy activist group Anonymous published the name of the officer it believes responsible for the shooting. Earlier, the group claimed to have hacked the city servers and obtained dispatch recordings and other information.

Jackson later said the group had the wrong officer. CNN is not reporting the name.

Brown’s family members say they’re frustrated with the lack of information from police.

“We’re still looking for answers,” cousin Eric Davis said. “They have not been transparent in any shape, form or fashion. We’re in the dark.”
