The article attempts to determine what it is about resident/police relations in poor urban communities that results in many community members' deep distrust of police. The article uses a framework of the "four trust questions" to analyze the complexities of community members' perceptions of police and police action aimed at reducing youth violence in Boston's high-crime neighborhoods. To differentiate residents' multiple -- and sometimes conflicting -- expectations of police, the article divides trust into four questions about priorities, competence, dependability, and respectfulness. The article is based on more than 50 qualitative interviews with youth ages 13 to 24, parents or adult caretakers of youth ages 13 to 25, and professional youth workers or frontline staff of community organizations who work with youth on a daily basis. Many residents considered that police met their expectations of competence and dependability but not of shared priorities or respect. Respect, in particular was important to residents, although they recognized a tension between police acting competently and respectfully. Table, notes, references
