A plaintiffs attorney on Monday urged the U.S. Court of Appeals for the Ninth Circuit to hold Google Inc. accountable for uploading data from private Wi-Fi networks as part of its Street View program, saying that even the U.S. government has stopped short of such surveillance techniques.

If the court accepts Google’s argument that Wi-Fi signals are "radio communications" exempt from the federal Wiretap Act, "that loophole is big enough for massive government intrusion," Lieff Cabraser Heimann & Bernstein’s Elizabeth Cabraser argued.
