Zohran Mamdani might point to Sunday morning’s events in Flatbush as exactly what he’s thinking of when he says he’ll order the NYPD not to respond to most domestic-violence calls, sending social workers instead: After all, the subject of the complaint wound up shot dead by responding officers.

Except that it turned out the guy was carrying, though his victim didn’t know when she rang 911 for help as an ex she’d gotten a protection order against was banging on her door.

She’d plainly told him the police were coming, as he was on his way out of the building, gun in hand, when six officers showed at the scene.

They called on him to drop the weapon; he fled instead.

The cops pursued, shouting about a dozen times for him to disarm, before one of them shot to bring him down; they wound up rushing him in their squad car to Kings County Hospital, where he was pronounced dead.

Mamdani might say this proves his point (a policy he still holds even after softening some of his other anti-police rhetoric) that cops shouldn’t be answering domestic-violence calls at all; we beg to differ.

In Mamdani’s ideal New York the 911 dispatcher would tell the woman, We’ve got a crack team of social workers on the way!

If the victim relayed that info to the guy furiously trying to bust into her home (this was the third time she’d called 911 on him, by the way), would he leave — or try even harder to get in?

And what would he do, gun in hand, if the social-work squad confronted him?

He was in a bad enough state that he fled the police — though they’d likely have picked him up eventually anyway, since he’d been ID’d and seen with the gun. (This, when many let-em-loodse city judges wouldn’t even jail him if he’d surrendered.)

Surely he might have fired on mere social workers — who, again, would be rushing to the scene unaware anyone was armed.

Domestic violence calls are among the most fraught: Men who beat women are all too prone to do much worse, and a man who persists after being rejected by a woman is already in a disturbed state of mind.

Yet those responding to the call rarely have much information — an address, a description of the perp and perhaps a few other words; in an emergency, they don’t have time to check the case file.

Sure, social workers can play a helpful role in addressing domestic violence — but not in the heat of the moment.

This is just another no-brainer that Mamdani and his privileged pack of social-justice theorizers never bothered to think through.

Just as he plainly didn’t think for a moment before his selfie with Rebecca Kadaga, Uganda’s deputy prime minister, during his July trip to celebrate his wedding in the family compound.

Did he know she’s taken credit for ramming through her nation’s harsh anti-gay laws? Surely he’d at least aware of the policies of the ruling party, if only to caution any gays he invited to the celebration.

New York City really doesn’t need a mayor whose mind is focused on selfies and YouTube videos, a man with lots of airy ideas but not a clue about how the other half lives.
