Christine Quinn has long said she would keep Ray Kelly on as police commissioner, though she’s no fan of stop-and-frisk. On Wednesday, she was already threatening to fire him if he couldn’t get the number of stops down: “If you can’t agree to that, don’t take the job, and if you take it and you don’t do it, you’ll get fired,” Quinn said at a NY1 mayoral debate. Let’s hope she has a second choice in mind for the position.
