Brad Pitt has thrown his weight behind a documentary that blasts America's 40-year war on drugs as a failure, calling policies that imprison huge numbers of drug-users a charade" in urgent need of a rethink. The Hollywood actor [recently became] an executive producer of filmmaker Eugene Jarecki's "The House I Live In," which won the Grand Jury Prize in January at the Sundance Film Festival. The film opened in wide release in the United States on [October 12]. Ahead of a Los Angeles screening, Pitt and Jarecki spoke passionately about the "War on Drugs" which, according to the documentary, has cost more than $1 trillion and accounted for over 45 million arrests since 1971, and which preys largely on poor and minority communities. "It's such bad strategy. It makes no sense. It perpetuates itself. You make a bust, you drive up profit, which makes more people want to get into it," he added. "To me, there's no question; we have to rethink this policy and we have to rethink it now." "The House I Live In" was filmed in more than 20 states and tells stories from many sides of the issue, including Jarecki's African-American nanny, a drug dealer, narcotics officer, inmate, judge, grieving mother, senator and others. It also shows that although the United States accounts for only 5 percent of the world's population, it has 25 percent of its prison population. Additionally, African Americans, who make up roughly 13 percent of the population and 14 percent of its drug users, account for 56 percent of those incarcerated for drug crimes.
