Hacking group Anonymous vow to name cop who shot dead teen

The hacking group Anonymous has made a pledge to help the family of an unarmed black teen gunned down by police in the US.

The shooting of the unarmed African-American teenager prompted two nights of looting and unrest in the boy's hometown of Ferguson City in the state of Missouri.

Under the Twitter hashtag #OpFerguson, the group say the death of 18-year-old Michael Brown is the latest example of extreme injustice being inflicted on “everyday” American citizens.

On Wednesday they released a video stating the vigilante organisation’s intent to name every officer and official involved in what it states is an illegal cover-up.

The group has a history of waging campaigns against what it perceives as corrupt law enforcement officials and say they are going where the media isn’t allowed to go.

Michael Brown's father is mourning the loss of his son but has echoed pleas for peaceful protests amid heightening racial tension, rallies and looting.

"I need all of us to come together and do this right... no violence," Michael Brown Sr told a news conference in St Louis, Missouri.

His son was unarmed when he was shot dead during a confrontation with police.

Investigators have released few details, saying only that the shooting was preceded by a scuffle between the officer and a man in which the officer's weapon fired inside a patrol car.

Witnesses say Brown had his hands raised when the officer repeatedly shot him in the predominantly black city of about 21,000 residents.

The officer was placed on administrative leave but police say death threats prompted them to withhold the officer's name.

Ferguson Police Chief Tom Jackson said he'd planned to release the officer's name but changed course after death threats were called into the police department and City Hall, and posted on social media. Jackson said it could be weeks before he releases the name.

"If we come out and say, 'it was this officer,' then he immediately becomes a target," Jackson said. "We're taking the threats seriously."

The race of the officer also hasn't been disclosed, but witnesses said he was white. Brown was black.

Civil rights leader Reverand Al Sharpton pressed police to release the name of the officer involved in the shooting but also pleaded for calm after two nights of violent protests.

"The local authorities have put themselves in a position — hiding names and not being transparent — where people will not trust anything but an objective investigation," Sharpton, standing with Brown's parents, said during a news conference in St. Louis.

President Barack Obama released a statement also urging calm, saying people must comfort each other "in a way that heals, not in a way that wounds."

Nearly three dozen people were arrested following a candlelight vigil on Sunday after crowds burned stores, vandalized vehicles, assaulted reporters and taunted officers.

Yesterday, there was no looting but officers arrested at least five people and used tear gas and "beanbag rounds" on a large, rowdy crowd at a burned-out convenience store after rocks were thrown at police.

"People are tired. They have reached the end of their rope," Ruth Latchison Nichols said after a town meeting that drew hundreds of people.

"Enough is enough. This is a state of emergency."

One shooting witness, Phillip Walker, told The Associated Press he was on the porch of an apartment complex overlooking the scene when he saw a white officer with Brown, who was "giving up in the sense of raising his arms and being subdued."

Walker said the officer "had his gun raised and started shooting the individual in the chest multiple times." He said the officer then "stood over him and shot him."

Dorian Johnson offered a similar account, telling local media that he and Brown were walking home when a police officer told them to get out of the street and onto the sidewalk. Johnson said they kept walking, which caused the officer to confront them and eventually fire his weapon.

"He shot again, and once my friend felt that shot, he turned around and put his hands in the air, and he started to get down. But the officer still approached with his weapon drawn and fired several more shots," Johnson said.

Police have said there was no security or police video of the incident.

The family's attorney, Benjamin Crump, has asked individuals with video of the shooting to come forward.

Crump also represented relatives of Trayvon Martin, the 17-year-old fatally shot by a Florida neighbourhood watch organiser who was later acquitted of murder charges.

"I don't want to sugarcoat it," he said Monday.

"(Brown) was executed in broad daylight."

St. Louis County police are leading the investigation, and the Federal Aviation Administration agreed to order flight restrictions over Ferguson to give police helicopters unfettered access to that air space.
