BOB MCMANUS: NYC finally takes a stand: End this surrender to crime.

New York’s mayor-elect got a credibility test Wednesday, and passed handsomely. Here’s hoping Manhattan’s next district attorney was paying attention.

In normal times, Black Lives Matter bigmouth Hawk Newsome’s promise to bring rack and ruin on the city if Eric Adams doesn’t cede the streets to gangbangers on Jan. 1 could be dismissed as ugly street theater.

“If they think they are going back to the old ways of policing then we’re going to take to the streets again,” Newsome declared after Adams promised to aggressively combat gun crime. “There will be riots. There will be fire. There will be bloodshed.”

But we live in stupid times, in a city that stood supinely as a landmark department store, Macy’s Herald Square, was looted the last time BLM got a mad on. And in which Alvin Bragg. the candidate for district attorney who promised to be even softer on crime than the marshmallow Cyrus Vance Jr., will take office alongside Adams.

And so Newsome’s ugly threats must be taken seriously. . . .

Adams has drawn a line: “I’m going to put in place a plainclothes gun unit,” he responded Thursday.

Newsome has promised to cross it.

Assuming each man is as good as his word, and given the uncertainties of effective police work, a collision is inevitable — the date, location and circumstances to be determined.

Sounds to me like there’s a better claim that Newsome is waging an insurrection than there is against any of the J6 protesters.
