It's like a bad dream that keeps coming back. Google has admitted that it still has some Street View data that Britain's Information Commissioner's Office told it to get rid of in 2010.
This article from Naked Security notes Street View is generated in part from Wi-Fi data collected by cars that drive around communities for Google collecting location data. Users can then triangulate a location on Google Maps. But there is no reason for Google to store data from private networks. It has promised officials in a number of countries to delete the data, but last week admitted it hasn't scoured its databases enough.
Just a reminder that in May some U.S. congressmen urged the Justice Department to re-open its investigation into the Street View matter there.
