Massachusetts Democrats have a bold new proposal for prisoners: donate your organs or bone marrow, and get as little as a couple of months off of your sentence. The legislation, which has attracted five cosponsors in the state house, raises major bioethical concerns for the six-thousand-plus people currently held in the Bay State’s prisons. In essence, the bill would ask prisoners which is more important to them: their freedom, or their organs and bone marrow.

The bill appears to go significantly beyond other organ-donation policies for prisoners. The Federal Bureau of Prisons says that prisoners may donate their organs while incarcerated, but only to immediate family members. In 2013, the State of Utah allowed organ donation from prisoners who died while being incarcerated. Most other states do not allow organ donations from prisoners at all.

The Ethics Committee of the United Network for Organ Sharing, the nonprofit that administers organ transplants in the United States, has panned proposals like the Massachusetts bill. “Any law or proposal that allows a person to trade an organ for a reduction in sentence . . . raises numerous issues,” the committee says in a position statement on their website.
