 Some traditional free speech advocates such as the British Columbia Civil Liberties Association have cautiously sided in favour of narrowly defined "bubble zones" around abortion clinics on the basis that patients have a medical right to privacy when receiving confidential legal medical procedures that is compromised if protesters identify patients for the purpose of publicly shaming or intimidating them.The American Civil Liberties Union helped enact the Freedom of Access to Clinic Entrances Act in 1994, which guarantees pedestrian access to clinics, but does not restrict related speech activity.In "Schenck v. Pro-Choice Network of Western New York", the ACLU filed briefs defending the constitutionality of a court order that prohibited defendants from protesting within 15 feet of clinic driveways and entrances in western New York.
