The court's ruling was more nuanced and narrow than what is reported at the link.
"We do not eliminate flight as a factor in the reasonable suspicion analysis whenever a black male is the subject of an investigatory stop. However, in such circumstances, flight is not necessarily probative of a suspect's state of mind or consciousness of guilt. Rather, the finding that black males in Boston are disproportionately and repeatedly targeted for FIO [Field Interrogation and Observation] encounters suggests a reason for flight totally unrelated to consciousness of guilt. Such an individual, when approached by the police, might just as easily be motivated by the desire to avoid the recurring indignity of being racially profiled as by the desire to hide criminal activity. Given this reality for black males in the city of Boston, a judge should, in appropriate cases, consider the report's findings in weighing flight as a factor in the reasonable suspicion calculus."
The court specifically stated they were not eliminating flight as a factor in the reasonable suspicion analysis when a black subject is stopped on the basis of fleeing. The court is explicitly stating flight is still a factor in determining reasonable suspicion and this is applicable to blacks. The court's ruling instructs lower courts to consider another factor in addition to flight in regards to blacks.
