Deconstructing 'Legal Abortion Saves Lives'
As you can see from the graph below, abortion deaths were falling dramatically before legalization. If you look closely you can see the points where New York and California legalized abortion on demand, as well as the point where Roe v Wade was handed down. Though annual abortion deaths did indeed fall after legalization, this fall had been in place for decades. To argue that legalization lowered abortion mortality simply isn't supported by the data.
