In August of 2013, a federal district court found that New York City's stop and frisk policy was unconstitutional because of the way it singled out young black and Hispanic men. Later that year, New York elected its first liberal mayor in 20 years. Bill DeBlasio celebrated the end of stop and frisk. But he did not do away with broken windows. In fact, he re-appointed Rudy Giuliani's police commissioner, Bill Bratton.
