Apparently your iPhone won't direct you to certain medical services like abortions or clinics for emergency contraception.
Quote: If you ask Siri for an abortion clinic in New York City, it will tell you "Sorry, I couldn't find any abortion clinics." A simple Google web search—which Siri itself uses to find results—gives you seven to start with, some within walking distance of where I'm located.
If you ask the same question in the city of Washington DC, Siri won't direct you to a nearby clinic, but to one 26 miles away.
Is Siri Pro Life? Apparently Yes.
