Examines the activities to crack down on the homeless in 50 U.S. cities despite the lack of resources to shelter homeless people or to help them become self-sufficient. Actions that penalize homeless people or their activities have continued in many cities during the last two years, although in several cities, officials are taking steps to address concerns about homeless people's use of public spaces constructively, rather than simply penalize homeless people. Chapters: enforcement trends: local analyses; the criminalization of homelessness as public policy; alternatives to criminalization; selected case law; & list of cities.
