A Kennedy family charity plans to spend millions of dollars to spring every bail-eligible city inmate that is 16, 17 or a woman in an epic move to promote jail reform, law enforcement sources told The Post on Tuesday.

The initiative would free hundreds of defendants — many awaiting trial for violent crimes including attempted murder, aggravated sex abuse and assault — from Rikers Island, The Tombs and other city lockups, sources said.

Robert F. Kennedy Human Rights could begin dispensing get-out-of-jail-free cards as early as Monday, the source said.

Law enforcement sources slammed the scheme, arguing suspects will have no incentive to actually show up in court if they aren’t on the hook for bail money.

“If a relative puts their house up for bail, the odds are pretty good that the arrested person will show up in court,” fumed one source.

“The odds are not that good if some rich person puts up the money. You won’t feel as obligated to show up.”

A high-ranking police source called the scheme “disgraceful.”

“If a high bail is set, that means the police and DA feel strongly that they committed the crime; that they will probably serve some kind of criminal sentence; and lastly they would be a flight risk.”

A city government source confirmed several hundred people could be freed.

The RFK foundation asked the city for a list of women and teens with unpaid bail, but the city has yet to provide the rundown, sources said.

Mayor Bill De Blasio spokeswoman Natalie Grybauskas said they hadn’t seen a specific plan from RFK, but, “We support any effort that focuses on bail assistance for low-level offenders who don’t pose a public-safety risk.”

A law enforcement source said 231 of the 419 women in city jails are currently eligible for bail — including 93 in Manhattan, 52 in Brooklyn, 28 in the Bronx, 40 in Queens and 18 on Staten Island.

Less than 100 teenagers would qualify, the source added.

Bail is set by a judge, and anyone can pay it, but defendants who do not have a bail amount — such as those remanded to jail or serving out a sentence — are not eligible.

The RFK foundation has made bail reform a centerpiece of its advocacy. The group sprung teenager Pedro Hernandez from Rikers last year when he became the poster child for bail reform while locked up more than a year awaiting trial on a gun charge.

RFK then “leveraged the widespread media and public attention to create a powerful advocacy moment for bail reform across New York,” the group gushed in its 2017 annual report.

Last year, the foundation raised $103,252.45 to bail 50 teenagers out of Big Apple jails ahead of the first day of school, the report noted.

The foundation has $5 million on hand to fund the latest bailout plan, sources said.

But it’s not clear how far that money will go — one potential recipient currently cooling her heels in Rikers is being held on $999,999 bail for the drug overdose death of her 5-year-old son.

The RFK foundation did not respond to requests for comment.
