GigaOM noticed that Apple quietly released an update to Siri that offers to put a user in contact with the National Suicide Prevention Lifeline, should he or she mention suicide. Should the person decline the offer, Siri then brings up area suicide prevention centers in a second attempt to provide resources.
As GigaOM notes, Google has had this search since 2010. Apple noted in its customer privacy statement on Tuesday that among the most common requests from law enforcement are ones from police hoping to prevent suicide.
