Punch a Guard and Walk?

It’s not just the RFK Human Rights dogooders who look awful in the case of Rickeem Parker: Team de Blasio has some explaining to do, too.

Parker, 18, was released despite having punched out a correction officer. And he was being held on $1,500 bail because of his violent history, with eight arrests on charges such as assault, robbery, fraud and weapons possession.

Now he’s back on the streets, thanks to the RFK crew, whose “mass bailout” supposedly didn’t apply to males over 17.

At least two other RFK beneficiaries have already failed to return for their scheduled court appearances: Neither Tamika West nor Ralphie Myree has been seen since.

But it’s the city that needs to explain why Parker wasn’t re-arrested for assaulting the guard. Why didn’t the Department of Correction tell the Bronx DA about the attack until The Post broke the story Monday — al- most a month late and after Parker had been released on bail? Did City Hall give DOC special instructions on teen perps?

DOC is already struggling to contain gangrelated brawls at the Horizon youth-detention facility in The Bronx, where 16-yearolds are being held separately to comply with the new Raise the Age law.

Among other unintended consequences, Raise the Age seems to have teens thinking they’ll face no consequences for jailhouse violence — and the Parker case looks to confirm that mindset.

Again, we support criminal-justice reform — done thoughtfully. The simplistic RFK stunt ignores the potential harm that ticking time bombs like Parker represent.

One of his victims, Samuel Scott, spelled out the danger to The Post: “It’s like giving someone a free pass to destroy other people.”

City Hall, meanwhile, needs to publicly explain what orders it’s given to DOC.
