Policing in Arab-American Communities After September 11 reports on a study examining how the terrorist attacks of September 11, 2001, affected relationships between law enforcement officers and residents in Arab-American neighborhoods. Four significant obstacles to improved relations between police and Arab-American communities were observed: mutual distrust between Arab-American communities and law enforcement, lack of cultural awareness among law enforcement officers, language barriers, and residents' concerns about immigration status. The study reveals some promising practices for addressing these obstacles.
