Now That’s Confusion

In States of Confusion in today’s New York Times, we find the following paragraph:

Abortion-rights states would undoubtedly respond in kind [if other states made out of state abortion a crime]. For example, Rhode Island, where 63 percent of residents favor abortion rights, has rebuffed efforts at regulation in the past. Just as Utah could make it a crime for a resident to go to Rhode Island for an abortion, Rhode Island could forbid Utah’s law-enforcement officials from interfering with her decision to get one. Similarly, if an anti-abortion state places a fetus in protective custody, an abortion-rights state might do the same for the woman. And so on.

How does putting a woman in protective custody help her?
