Except when he didn’t. Good Ol’ Kerik, even when caught red handed, can’t help being a straight up scumbag.

Bernard Kerik became the first NYPD commissioner to land in jail Tuesday after a judge revoked his bail for trying to taint the jury pool in his upcoming corruption trial.

Late last night Kerik was taken from White Plains Federal Court to the Westchester County Jail in Valhalla. His lawyers vowed a prompt appeal to try and get him out.

A furious Judge Stephen Robinson threw Kerik in the clink after prosecutors said the former top cop and the head of his legal defense fund engaged in a subversive campaign to sway potential jurors.
