Washington - The white former Ferguson police officer who shot dead an 18-year-old unarmed black teenager has given his first published comments since the controversial shooting that reignited a discussion about race in America.Twenty-nine-year-old Darren Wilson spoke with New Yorker magazine from St Louis, Missouri, where he is laying low after the uproar triggered by his shooting of Michael Brown on August 9, 2014.Wilson was cleared of wrongdoing by a grand jury and the federal government. But the shooting, the circumstances of which are disputed, touched a nerve in American society and ignited sometimes violent protests and heavy-handed policing in response.In the lengthy article published on Monday Wilson expressed little emotion over the killing of Brown."Do I think about who he was as a person? Not really, because it doesn't matter at this point. Do I think he had the best upbringing? No. Not at all," he told the magazine.

"What happened to my great-grandfather is not happening to me. I can't base my actions off what happened to him.""Everyone is so quick to jump on race. It's not a race issue," he told the magazine, adding that the real issue under discussion was police power.The reporter noted that Wilson at times seemed to use "racial code language.""They're so wrapped up in a different culture than - what I'm trying to say is, the right culture, the better one to pick from," Wilson said about policing a black community. Wilson's shooting of Brown has drawn attention to the police's use of force, particularly in its dealings with black suspects.A string of police killings of black suspects since the shooting in Ferguson has caused an outpouring of anger at perceived police racism and prompted calls for change.
