The highest court in Massachusetts on Tuesday threw out a gun conviction against a Boston man in a ruling that says black men who flee when approached by police may be reacting to racial profiling rather than trying to hide criminal activity.

In its ruling, the Supreme Judicial Court found that Boston police had "far too little information" to stop Jimmy Warren after seeing him and another black man walking in Boston's Roxbury neighborhood about 30 minutes after they received a report of a home break-in in 2011.

Police had received only a vague description of three black males wearing dark clothing and hooded sweatshirts seen leaving the home. Warren ran when police approached him. After a foot chase, an officer arrested him in a backyard. He was charged with unlawful possession of a firearm after a handgun was found on the front lawn.

The SJC found that police did not have a reasonable suspicion to stop Warren and his friend, noting that an officer's hunch is not enough. The court cited a report by the Boston Police Department that found black men were disproportionately stopped and frisked by Boston police between 2007 and 2010. The court said black men in Boston who flee when approached by police does not necessarily indicate that they are guilty of a crime.
