BOB MCMANUS: With O’Neill’s resignation, who’s going to clean up de Blasio’s mess now? “Who wants to be top cop in a city that appears to have lost the will to defend itself from criminals and their ever-present, ever-more-audacious advocates? And make no mistake: The criminal-justice agenda concocted in Albany last winter and now embraced so ardently by Gotham’s leaders — bail ‘reform,’ jail closing, tolerance for public disorder and so on — represents a not-so-subtle surrender to the city’s worst instincts.”

Plus: “Open contempt for the NYPD is a thing now. They were pouring water on cops — and, once, even a carton of milk — this summer because they had every reason to believe they could get away with it. And, by and large, they were right. Now they’re trashing cop cars in public; marching by the hundreds in Brooklyn to spew vile anti-NYPD invective; openly defying officers in the subways and on the streets — and basically they’re getting away with that, too.”
