A couple from Pittsburgh has sued Google because a photo of their house appeared on Google Street View. They are demanding in excess of $25,000 to make up for the 'mental suffering' and the diminished value of their home. Their street is apparently marked with a 'Private Road' sign, and they claim that putting a photo of their property online is an 'intentional and/or grossly reckless invasion' of their privacy. Google, on the other hand, claims that this lawsuit is pointless since anyone can ask them to have pictures removed without legal action.
Well, since it was a private road, I don't think that legally Google was in the clear. If the photos were taken from a public road, they would be fine.
