Need help with Planned Parenthood protestors : WitchesVsPatriarchy

Depending what state this is in, the protesters might be barred from protesting directly outside the Planned Parenthood building by buffer zone laws and that's why they're outside her office:

States have taken two approaches designed to protect abortion providers. Some states have enacted laws similar to the federal FACE Act that prohibit specific activities such as vandalism or obstruction at clinics. Other states have limited protests aimed at clinic patients by either creating "buffer" zones around clinics that bar protestors entirely or establishing floating "bubble zones" of several feet around a person who is within a specific distance of a clinic; protesters are prohibited from crossing into that "bubble zone" without the person's consent. In 2014, the U.S. Supreme Court struck down the Massachusetts law that placed a 35-foot buffer zone around clinic entrances. The impact of this ruling on the New Hampshire law is still to be determined, but the decision did not immediately affect the Court's 2000 ruling that upheld Colorado's floating "bubble zone" law.

So, for example, in Colorado protestors can't come within "8-ft. zone within 100 ft. of door", i.e. they can't come within 8 feet of a person who is 100 feet away from the door of the clinic. That could be why the protestors are confined to that part of the car park outside the next door office building.
