The worst part about this is that the NY Post has become the voice of reason and intelligence over this issue: Police Commissioner Bill Bratton needs to shut up and focus on his job. He’s making a fool of himself with his finger-pointing media appearances. Set aside the flap over his interview with the UK Guardian; he claims he was misquoted. He can’t make that excuse about his pathetic remarks Wednesday on the John Gambling show. On live radio, he blamed the NYPD’s current problems on . . . fatherlessness in minority communities. As if that’s anything new. As if the issues presented by what he termed “homes dissolving and homes without parental guidance” weren’t just as bad back in 1994, when Bratton first took command of the NYPD. Sorry, Commissioner: What’s changed isn’t the families or the communities. It’s the politicians. In ’94, New York’s elected leaders — Mayor Rudy Giuliani, City Council Speaker Peter Vallone — had the backs of every officer on the force. Today’s leaders — Mayor de Blasio, Speaker Melissa Mark-Viverito — clawed their way into power by bashing the cops every chance they got. And proceeded to re-elevate racial arsonists like Al Sharpton, along with all he represents. The cops know it. That’s why so many of them were so publicly turning their backs on the mayor just a few months ago. That’s why, as Bratton himself put it, “This is a police force that’s very unhappy.” He’s flat wrong to say, “They think the community doesn’t support them.” Nope: The cops know it’s the politicians who don’t support them. And minority communities support the policing the pols are attacking. Asked in the recent Quinnipiac poll if they want the police to “actively issue summonses or make arrests” in their own neighborhoods for quality-of-life offenses, 61 percent of the city’s blacks say “yes,” against 33 percent “no.” That was more support than among whites (59 percent to 37 percent). Sure, Bratton spoke a few irrelevant truths in his radio remarks. No doubt there is “less respect for authority” and for the “average police officer in the street” than in the days of stronger families. But those days were decades ago.
