. Attorney General Eric Holder expressed his concern with the number of African-American men who are serving longer sentences than white men for similar crimes. During his speech delivered at Rev. Al Sharpton’s National Action Network Conference on Thursday, Holder told the audience, “ I am concerned by a troubling report … which indicates that — in recent years — black male offenders have received sentences that are nearly 20 percent longer than those imposed on white males convicted of similar crimes .” The “troubling report” he is referencing is a recent report from the U.S. Sentencing Commission . According to the report, black men found guilty between December 2007 and September 2011 received sentences that were a whopping 19.5 percent longer than white men found guilty for similar crimes. “ Too many people go to too many prisons for far too long for no good law enforcement reason ,” Holder said. “ It is time to ask ourselves some fundamental questions about our criminal justice system. … It is time to examine our systems and determine what truly works .” Holder isn’t the only person interested in an overhaul of the judicial system. Rumors are sparking that Dr. Boyce Watkins and Russell Simmons have joined forces to place pressure on the White House to address mass incarceration. While the men have remained tight-lipped about specific requests they’re making, Dr. Watkins has listed a slew of prominent entertainers such as Scarlett Johansson, Kim Kardashian, Lil Wayne, Nicki Minaj, etc. who have joined he and Simmons in pushing the White House to tackle the matter. An official announcement about the demand is expected to be released this week. Although a number of people attribute mass incarceration of African-American men to prejudice, assistant law professor Lahny Rose Silva of Indiana University’s McKinney School of Law says it is impossible to prove whether or not the report’s findings are attributed to racial bias on the part of the judges. “ How do you prove racial bias without an individual coming out and blatantly saying ‘I‘m using race as a factor in sentencing ?” Silva says. “ You just don‘t do it .” She added that black men have largely received longer sentences than white men throughout the nation’s history and that the report shows nothing out of the ordinary from previous sentencing records. Do you believe mass incarceration will come to an end?
