Buffer zones were created in Massachusetts after a 1994 tragedy in which a gunman, John Salvi, killed two clinic employees and wounded five others.
Massachusetts passed its first buffer-zone law in 2000, establishing an 18-foot zone. That law included a “floating zone” that allowed anti-abortion advocates to move closer, Moran said.
The distance was increased to 35 feet several years later.
The Supreme Court will issue a ruling by June.
