In a letter to the UK Information Commissioner, Google has admitted it retained payload data improperly collected by Street View vehicles. Google had promised earlier it would delete the data. The UK privacy agency has now demanded that Google turn over the payload data for examination and forensic analysis. EPIC recently filed an amicus brief in a US federal appeals court, arguing that Google Street View violated federal wiretap law.
