First of all, they shouldn’t ask.
“As a basic principle, we can’t tell you to stop recording,” says Delroy Burton, chairman of D.C.’s metropolitan police union and a 21-year veteran on the force. “If you’re standing across the street videotaping, and I’m in a public place, carrying out my public functions, [then] I’m subject to recording, and there’s nothing legally the police officer can do to stop you from recording.”
“What you don’t have a right to do is interfere,” he says. “Record from a distance, stay out of the scene, and the officer doesn’t have the right to come over and take your camera, confiscate it.”
Officers do have a right to tell you to stop interfering with their work, Burton told me, but they still aren’t allowed to destroy film.
Yet still some officers do. Last week, an amateur video appeared to show a U.S. Marshal confiscating and destroying a woman’s camera as she filmed him.
