“Capt. Coan would tell the field team . . . ‘They are f——-g animals. You make sure if you have to shoot, you shoot them in the head. That way there’s one story,’ ” said the retired detective.

The ex-cop, identified only as Undercover 7988, said Coan’s racist rant came before every search warrant executed in Brooklyn’s Brownsville, Bedford-Stuyvesant and East New York from 2008 to 2010.

“They didn’t care if it was kids in there, they didn’t care if it was women in there, naked women,” the detective said. “. . . They treated them as if they had no rights whatsoever. It was disgusting."
