The report, which was just recently made public, showed that, on average, black men spent almost  20 per cent more time in prison between December 2007 and September 2011. In addition, white males were more likely to serve sentences below the sentencing guidelines while black men were 25 per cent less likely, according to the commission. Among recommendations, the commission advised judges to follow sentencing guidelines and suggested that the federal appeals court  reconsider those sentences that do not fit the sentencing guidelines.
