In 1994, John Salvi, a radical young Catholic abortion opponent, opened fire on two clinics in Brookline, Mass., just outside Boston, and killed two women: Shannon Lowney, a 25-year-old receptionist at Planned Parenthood, and Lee Ann Nichols, who worked as a receptionist at PreTerm, the clinic down the street.

The killings ignited a fierce debate about the intersection of free speech, abortion and religion, a debate reignited by the recent Supreme Court decision overturning a buffer space around clinics in Massachusetts. For the first time, the 1996 Frontline documentary Murder on Abortion Row is streaming online.
