Private philanthropic support for government agencies continues to expand into different areas of public services, especially at the local level where libraries, parks and recreation departments, and police departments have benefited. The resources generated by a dedicated government-supporting nonprofit can play a significant role in enhancing the work of government, not only through resources, but through community engagement. In this article, we focus on police foundations, registered 501(c)3 nonprofits that exist to support police departments. Using NCCS nonprofit data and data collected from organizational websites, we create a database of 243 police foundations that identifies their mission statements, websites and activities, and the characteristics of the communities in which they are found across the U.S. In doing so, we argue that, rather than government failure or inadequacy to meet the needs of communities, police foundations are the result of isomorphism among professionalized police departments seeking to enhance their work and connection to the community. While funding for additional equipment and training are the most common activities of police foundations, the similarity in programs serving the community gives some indication of the proliferation of best practices in public safety.
