If she traveled to a state where abortion is legal and has the abortion there, she hasn’t committed a crime in the state where abortion is illegal.
Kind of surprised some people are talking along the lines of states limiting where people can travel (or even monitoring where they travel). The freedom to travel between states unmolested has been one of our core liberties since the beginning, right up there with the right to bear arms and the right to free speech.
in a state where abortion is illegal, she would be seen as the guardian of the child.
if that child suddenly went missing, a murder investigation would have to be held.
if she were found to have traveled somewhere to carry out her plans to have the child killed, she would be responsible for the murder... regardless of the laws of that state or country... as she lives under the laws of the anti-abortion state
