But what about when that person is taking pictures of everyone's houses and posting those pictures online? They may not have been intending to invade your privacy, just show a picture of all the houses in the neighborhood.

There is a difference between the the million of little pieces of private information we leak every day and the collection and preservation of that data. Google is doing the right thing here and is going to delete this data and make sure they don't collect it again, but I think you are wrong to dismiss the collection of private data as unserious.
