There are few — if any — universally applicable solutions to the issue of homelessness

• Although poverty and the lack of affordable housing are considered the key variables at play, homelessness can manifest differently across the country. Some areas have more challenges with unsheltered homelessness, particularly in locales with a mild climate, while other communities might experience challenges related to sheltered populations. The specific needs of these populations might not be the same.

Homelessness is intertwined with other challenges, such as mental illness and substance use

• Police often have limited response options beyond taking people to jail or a hospital. Without the necessary systems to remedy the underlying causes of these frequently co-occurring issues, PEH often cycle in and out of the criminal justice system. Even when resources are available, those in need might consistently decline services.

Law enforcement is not equipped to address the underlying causes of homelessness

• Police must balance the lack of tools and resources to respond in a meaningful way with pressure from the community and business leaders to "do something" about homelessness, while also respecting the legal rights afforded to PEH. Collaborative efforts among law enforcement, other government agencies, social services providers, and community leaders are key to ensuring that individuals are connected with appropriate services.

Experts noted a need for a clear research agenda

• Data gathered using a comprehensive research agenda would inform new programs, and ongoing data analysis would help define the nature of homelessness in each jurisdiction, inform solutions to fill gaps or needs left unaddressed by existing responses, and evaluate whether new approaches achieve intended outcomes.

Police often are the first (and sometimes the only) point of government contact for persons experiencing homelessness (PEH). Although it has been common for police to rely on traditional law enforcement powers in dealing with homelessness, many agencies have moved away from arrest-focused methods in favor of approaches that are designed to foster positive relationships with PEH, assess individual needs of each person or area, and guide homeless or unsheltered individuals to the services they require.

To better understand the potential challenges of the law enforcement response to homelessness, the RAND Corporation and the Police Executive Research Forum, on behalf of the National Institute of Justice, convened a workshop of practitioners and researchers to discuss current law enforcement responses to homelessness and identify the highest-priority needs to support and improve existing efforts. During this meeting, four major themes were identified. First, there is a common set of factors underlying homelessness that law enforcement can address. Second, homelessness and overall health and wellness are deeply intertwined issues that should be treated together. Third, effective responses require the collaboration of stakeholders across governments, the private sector, and the community. Finally, acquiring and sharing data is necessary to understand the nature and scope of homelessness in each jurisdiction and to measure the effect of any implemented strategies. All four of these themes are vital to understanding the current challenges confronting the implementation of innovative police responses to homelessness.
