The New York Police Department has secretly labeled entire mosques as terrorism organizations.
Since the 9/11 attacks, the NYPD has opened at least a dozen “terrorism enterprise investigations” into mosques. The TEI is a police tool intended to help investigate terrorist cells.
Designating an entire mosque as a terrorism enterprise means that anyone who attends prayer services is a potential subject of the investigation and fair game for surveillance.
Many TEIs stretch for years, allowing surveillance to continue even though the NYPD has never criminally charged a mosque or Islamic organization with operating as a terrorism enterprise.
