(CNN) -- A scathing review of policing in Boston found that in a city where about a quarter of the population is African-American, two-thirds of police stops involved black residents, according to the American Civil Liberties Union. The report, titled "Black, Brown, and Targeted," is based on the preliminary results of a study commissioned by the Boston Police Department -- which analyzed 204,000 "Field Interrogation and Observation" (FIO) reports from police officers between 2007 and 2010. "The fact that blacks make up about 25% of Boston's population, but are stopped 63% of the time raises serious concerns of racially biased policing," said Nusrat Choudhury, an attorney with the ACLU Racial Justice Program.
