This whole city is under a siege of cameras,” said Pritchett, a house painter who helps run a youth center in a low-income, high-crime neighborhood called Johnston Square. “In fact, they observed Freddie Gray himself the morning of his arrest on those cameras, before they picked him up. They could have watched that van, too, but no—they missed that one. I thought the cameras were supposed to protect us. But I’m thinking they’re there to just contradict anything that might be used against the City of Baltimore. Do they use them for justice? Evidently not.”
Pritchett had no idea that as he spoke, a small Cessna airplane equipped with a sophisticated array of cameras was circling Baltimore at roughly the same altitude as the massing clouds. The plane’s wide-angle cameras captured an area of roughly 30 square miles and continuously transmitted real-time images to analysts on the ground. The footage from the plane was instantly archived and stored on massive hard drives, allowing analysts to review it weeks later if necessary.
Since the beginning of the year, the Baltimore Police Department had been using the plane to investigate all sorts of crimes, from property thefts to shootings. The Cessna sometimes flew above the city for as many as 10 hours a day, and the public had no idea it was there.
A company called Persistent Surveillance Systems, based in Dayton, Ohio, provided the service to the police, and the funding came from a private donor. No public disclosure of the program had ever been made.
