The Massachusetts legislature passed legislation that created a 35-foot buffer zone around the entrances, exits, and driveways of abortion clinics. Four categories of people are permitted to be in those areas: 

(1) persons entering or leaving the facility;

(2) employees/agents of the facility acting within the scope of their employment;

(3) law enforcement or other emergency or repair personnel acting within the scope of their employment;

(4) persons using the public sidewalk or street to the facility for the purpose of reaching a destination other than such facility. Pro-life advocates challenged the constitutionality of the statute, claiming that it prevents them from gaining close personal contact with women that they wish to dissuade from seeking abortions. Does this statute violate First Amendment rights of the pro-life advocates? Explain.
