Democratic mayoral candidate Bill de Blasio met with NYPD Commissioner Ray Kelly for three hours on Thursday afternoon, and based on Mike Lupica's obsequious column in today's Daily News, things didn't go too smoothly.

Lupica, who has been a reliable and prolific mouthpiece for Kelly and the NYPD, complains that "de Blasio continues to insult Ray Kelly" at the peril of innocent New Yorkers, who are also ingrates, God Bless 'Em.

“People are somehow confident and complacent and accepting that the level of public safety we have in this city is a given,” Ray Kelly was saying Sunday. “I’m not sure they appreciate the effort and hard work in this department that made it happen, and continue to make it happen.”

Ray Kelly knows that we are mistaken about stop & frisk abuses and the creation of an inspector general (though curiously not about Muslim surveillance.) Deeply mistaken! Yet he still loves us and keeps us safe.

But with a single bite of that shiny, Obama-endorsed apple, we can be cast out of this resplendent garden.

“Maybe people will have a different opinion about things when violent crime goes up, and perhaps dramatically,” Kelly said Sunday. “Maybe that’s just life in the big city.”

Or death, that’s another way of looking at it.

Maybe murders will skyrocket again after Kelly leaves. Or maybe the crime rate will remain low and continue on its long, mysterious trajectory determined by myriad economic and societal factors. Maybe some other town that appreciates a successful police commissioner who also happens to be skilled in the art of casual passive-aggressiveness, will benefit from his expertise. Maybe.

In related news: Graham Rayman has an excellent primer on who might replace Kelly, assuming Republican Joe Lhota isn't elected. Don't sleep on former NYPD Chief of Patrol Wilbur Chapman, who plays a mean jazz Vibraphone (and is also, apparently, just plain mean).
