I don't know. Out of curiosity I just tried Find my iPhone on my own device which has been sitting in the same location in my house for about an hour completely untouched. Apple's interface shows my iPhone about a half mile away in a house I've never visited or been in before. There is a big circle around my device (which doesn't even include the actual location) but the actual dot is somewhere I've never been before. I've refreshed it about 5 times now 2-3 minutes apart and it is absolutely convinced that I am at that location. I avoided touching my iPhone during this experiment to mimic a real life scenario where the phone is out of reach. If I were in a scenario where I believed a family member was taken against their will to a location I would absolutely want a search, but this experiment makes it pretty clear why Find my iPhone is not probable cause to me.. Still trying to figure out why multiple 'pinpoint location' requests are showing somewhere about a half mile away from my real location. I would think that that type of request would push something to the phone which would power up GPS for accuracy, but it doesn't appear to be so.
