The surveillance debate triggered by Edward Snowden's leaks frequently features government spokespeople assuring Americans that the authorities aren't targeting us with their spying activities. Implicit is the notion that if Americans were being targeted, that would be an abuse of power.

In New York City, the debate is different, because there's no doubt about the NYPD's surveillance tactics: They're definitely targeting innocent Americans citizens and legal residents. And that's an ongoing abuse of power, even if comparatively fewer people have heard about it.

We've known for some time that innocent Muslim Americans were ethnically profiled by undercover NYPD officers, causing significant, under-acknowledged hardship in affected communities. Earlier this summer, Charlie Savage reported on four CIA officers embedded within the NYPD, despite the strict rules governing the spy agency's behavior within the United States. And today, New York has published "The NYPD Division of UnAmerican Activities," in which Matt Apuzzo and Adam Goldman unearth even more alarming details about the NYPD Demographics Unit.

Official secrecy defined the program from the start. "Documents related to this new unit were stamped NYPD SECRET. Even the City Council, Congress, and the White House -- the people paying the bills -- weren't told about it."

This is straight-up profiling. "They mapped, looking for 28 'ancestries of interest.' Nearly all were Muslim. There were Middle Eastern and South Asian countries such as Pakistan, Iran, Syria, and Egypt. Former Soviet states like Uzbekistan and Chechnya were included because of their large Muslim populations. The last 'ancestry' on the list was 'American Black Muslim.'"

Files on New Yorkers were started on the flimsiest of pretexts. "One Muslim man made it into files even though he praised President Bush's State of the Union address and said people who criticized the U.S. government didn't realize how good they had it. Two men of Pakistani ancestry were included for saying the nation's policies had become increasingly anti-Muslim since 9/11. Muslims who criticized the CIA's use of drones to launch missiles in Pakistan were documented."
