Could the headline-making arrest last July of Harvard African-American Studies Professor Henry Louis Gates by a white Cambridge, Massachusetts police officer be justified? While the official civil-rights narrative continues to cast Gates as a victim, the facts, as National Legal and Policy Center reported in detail at the time, appear to vindicate Police Sergeant James Crowley. Now a new report by a Boston University-affiliated journalism think tank is providing even more fuel for the latter view. The study, which examined arrests for disorderly conduct in Cambridge over several years, concludes that local police have not engaged in a pattern of racial profiling. One hopes that President Obama, who played no small role in this affair, will give it a close read.
