A Brooklyn federal judge read the riot act to a murderous drug dealer before slamming him with four life sentences in prison.

Gerard “Bloody Crime” Price, 31, who ran a drug trade referred to as the “Price-Pressley Enterprise” at Brooklyn’s Gowanus Houses, was convicted in April 2009.

“The Price-Pressley Enterprise imposed terror on a housing project,” Judge Nicholas Garaufis said. “They were tenacious, they were arrogant, they were vicious, they were violent.”
