In 1996, investigative journalist Gary Webb wrote a series of stories exposing the connection between the CIA and the crack cocaine that was being sold in South Central Los Angeles during the 1980s. These stories caused outrage everywhere, but the government denied the allegations and competing news outlets claimed the series was poorly written and contained false reports. But years later, it was revealed that the information written in Gary Webb’s series was true.
