The answer, of course, is that they couldn't—not legally, at least. Under the First Amendment, Americans have the right to observe and record members of the police force in the public discharge of their duties. Conversely, the NYPD’s right to conduct photo and video surveillance on citizens engaging in lawful protest is limited, with very few exceptions, to circumstances in which “it reasonably appears that unlawful conduct is about to occur, is occurring, or has occurred.”

Even as they mistreat photographers, police are continuing to subject these same citizens to illegal surveillance. When recordings are made for a purpose other than to record unlawful activity, police are supposed to avoid “close-ups of participants.” Yet peaceful marches are regularly lined with NYPD officers, cameras in hand, zooming in on individual faces. Even more egregiously, there has been at least one case this summer of police filming a protestor receiving medical treatment by EMTs.
From the earliest days of the occupation at Zuccotti Park, a police watchtower carried out round-the-clock surveillance of the protesters below. Almost a full year after the Occupy movement began, the watchtower remains, clearly communicating that “even if you’re not doing anything wrong, we’re watching.”
Under our laws and the Constitution, you have the right to film police without making yourself a target, and to engage in political speech and assembly without police surveillance (see the ACLU’s related resources here).
