This past weekend, 18-year-old African American, Michael Brown, was gunned down and killed by a police officer in Ferguson, Missouri. The shooting took place on a public street in front of horrified onlookers, who state the teen was unarmed and had his hands in the air in submission and surrender.

One witness stated of the victim to the Associated Press, "'He was giving up in the sense of raising his arms and being subdued. The officer 'had his gun raised and started shooting the individual in the chest multiple times.' The officer then 'stood over him and shot him' after the victim fell wounded."

The killing led to riots in Ferguson, as the public cried police brutality and racism in Brown's slaying. There were also peaceful protests and a candlelight vigil held in Brown's honor. An investigation is currently underway regarding the circumstances of the shooting. There is no justification for shooting an unarmed person, who had surrendered. That was an extrajudicial execution forbidden by law. 

Aug. 11, 2014 8:00 PM EDT - FERGUSON, Mo. (AP) — A black teenager who was fatally shot by a police officer had his hands raised when the officer approached with his weapon drawn and fired repeatedly, according to two men who said they witnessed the shooting that sparked a night of unrest in suburban St. Louis.

The FBI opened an investigation Monday into the death of 18-year-old Michael Brown, who police said was shot multiple times Saturday after being confronted by an officer in Ferguson, a suburb of 21,000 that's nearly 70 percent black.

Authorities were vague about exactly what led the officer to open fire, except to say that the shooting was preceded by a scuffle of some kind with a man. It was unclear whether Brown or the man he was with was involved in the altercation.

Investigators have refused to publicly disclose the race of the officer, who is now on administrative leave. But Phillip Walker said he was on the porch of an apartment complex overlooking the scene when he heard a shot and saw a white officer with Brown on the street.

Brown "was giving up in the sense of raising his arms and being subdued," Walker told The Associated Press on Monday. The officer "had his gun raised and started shooting the individual in the chest multiple times." The officer then "stood over him and shot him" after the victim fell wounded.

Dorian Johnson offered a similar account when he told WALB-TV that he and Brown were walking home from a convenience store 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 from his car and again after getting out of the vehicle.

Johnson said the first time the officer fired, he and Brown got scared and ran away. "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," Johnson said. "But the officer still approached with his weapon drawn and fired several more shots." "We wasn't causing harm to nobody," Johnson said. "We had no weapons on us at all." Walker said that he did not see a scuffle or the circumstances that preceded the first gunshot...
