The best and the worst of judicial wisdom were on display this week in two New York City courtrooms.

In one case, a veteran judge handed a would-be cop-killer the heavy dose of justice he so richly deserved.

“You will never step foot outside of a prison before you die,” vowed Queens Supreme Court Justice Gregory Lasak as he sent a cop-shooter away for 55 years to life.

The object of his ire: John Thomas, who gunned down Sgt. Craig Bier, a decorated hero cop, after being stopped by an anti-gang patrol back in 2012. Bier was hit twice in the legs and recovered.

“Who are you to take a gun and try to kill a New York City police officer?” the judge furiously demanded. That kind of anger has been lacking far too often of late as so many treat New York’s Finest as a political punching bag. So, good for Judge Lasak.

But then there’s Criminal Court Judge Stephen Antignani, who wouldn’t even impose the minimal $1,500 bail the Manhattan DA’s office asked for “Spider-Man” Jose Aguin.

Police said Aguin literally grabbed a youngster with whom he’d posed for a photo in Times Square and refused to let the boy go until his dad forked over $10.

Aguin was initially charged with aggressive panhandling, but the prosecution tried to add a charge of child endangerment.

No go, said the judge — prosecutors should’ve done that earlier.

He then assured Aguin he has “a right to dress up and take pictures with people.” As for taking the boy hostage, the judge said, “That’s not in front of me right now” — and sent Aguin on his merry way.

If the city ever gets around to setting up those designated “begging areas” in Times Square, it won’t make much difference if judges like Antignani keep putting a priority on panhandling thugs’ rights.
