Abortion-rights groups are nonetheless worried. If abortion were to become illegal in South Dakota, would the murder of a doctor performing an abortion suddenly become a justifiable homicide?
"That's a stretch is all I can say," Jensen told ABC News. "What it does is protect the mother who is trying to protect her unborn child. This covers cases where the mother's life isn't threatened but the unborn baby's is."
Still, not everyone is convinced the bill is necessary.
"The fact that this legislator would propose such a measure in a climate in which violence is being perpetrated against abortion providers and others (i.e., the folks in Arizona) is utterly shocking," Scott wrote.
For his part, Jensen said he is trying to protect the unborn, quite the opposite of inciting anyone.
