John Kass answers a whodunit, among a dozen other episodes listing this:
It wasn’t the police that sat on the video of Laquan McDonald, the black kid shot 16 times by a white cop until dead. It wasn’t police that refused to release the video until Emanuel was safe and had won a tough re-election.
Whodunit? The pols, Kass argues, and who are we to disagree?
