Ferguson police officer who killed unarmed teen says he has a clear conscience

The Ferguson policeman spared criminal charges after shooting an unarmed black teenager sparking rioting and protests across the US has spoken out for the first time, declaring he wouldn't change a thing.

In an exclusive interview on US television, Darren Wilson recounted the 90-second confrontation on August 9 that ended in him firing a series of shots at 18-year-old Michael Brown.

"I have a clear conscience," Wilson told ABC'S George Stephanopolous. "I know I did my job right."

When Stephanopolous asked Wilson if he could've done anything to prevent the shooting, he had one simple answer.

"No," he said.

Wilson denied that the incident was "haunting," and brushed it off as "something that happened."

He also denied that Brown had his hands up, a universal surrender symbol.

"No way, that’d be incorrect," he said.

He said he and his new pregnant wife, a fellow officer on the Ferguson police force, want to get on with their lives.

"We just want to have a normal life,” he said. "That’s it."

Wilson, 28, has been in hiding since August and the interview was reportedly held at an undisclosed location in the city of St Louis, 20 kilometres from Ferguson.

The interview comes as rioting and protests continue in Ferguson and across the US in response to a grand jury yesterday ruling Wilson acted in self-defence when he killed Brown.

A 20-year-old man has been reportedly shot dead just metres from where Brown was killed, while dozens have been arrested.

At least 12 buildings and two police cars have been set ablaze.

The demonstrations were expected to spread to 115 US cities by this morning.
