Street people include the homeless, alcoholics, mentally ill persons, runaways, and persons and families who have experienced economic hard times. Street people can cause problems for police by camping in public places, panhandling, or trespassing. They often fight among themselves, shoplift, sell drugs, mug passerby, and break into buildings. Their very presence often hurts area business. Police power to arrest the homeless is limited by court rulings. Police may either deal with them through a strict enforcement policy or by giving them the option to receive social services. A number of cities have forged alliances between police and the social service system in dealing with the homeless. Philadelphia; Boston, Mass.; San Diego, Calif.; Portland, Ore.; and the Port Authority of New York and New Jersey. These collaborative efforts are limited, however, by insufficient treatment facilities and shelters, the shabbiness of existing facilities, treatment limitations for alcoholics and the mentally ill, and some persons preference for living on the street. 6 references, discussion questions.
