But the details of how exactly police foundations spend their money are rarely public. And because they’re private nonprofits, they don’t have to report the names of their donors or where the money goes. When reporters and advocacy groups have pried information loose, they often find that a police foundation is supported by a small group of powerful interests. (The overwhelmingly white, wealthy board of the New York City Police Foundation “reads like an invite list for a party you’re not invited to,” Gothamist, a New York City news site, once put it.) They also find that police use these off-the-books budgets to expand some of law enforcement’s most questionable surveillance capabilities.
