Fresh Air Weekend: Novelist Richard Price says that in every precinct there's one cop who just can't let go of a case. "They all reminded me of Ahab ... looking for their whales," he says. Price's latest is called 'The Whites.' Then, David Remnick looks back on tough decisions as 'The New Yorker' turns 90. Remnick, who became editor in 1998, talks about his early days at the magazine and his biggest regret: He says he'd "love to have another crack" at covering Iraq's alleged weapons of mass destruction.
