People of the United Kingdom might have to keep an eye out, because your local police might be watching you. Not with a regular video camera. But with an infrared camera.
One night, a couple was caught in the act in the bushes of a local park by a police helicopter.
The man showed up white on infrared, so we can assume he was overheated and probably about to get too tired to reach the climax. Lucky for him, the authorities interrupted their outdoor adventure, so his friend can’t blame him for not finishing.
