mk1004 writes with news from The Register that U.S. Senator Charles Schumer of New York has written to Apple and Google regarding their use of 'military-grade spy planes.' The Senator claims concerns ranging from voyeurism to terrorism. Suggested protections: Warn when areas are going to be imaged, give property owners the right to opt out, and blurring of individuals. Schumer seems happy enough, though, with the more detailed versions of such surveillance being in the hands of law enforcement agencies, and phrases his complaint to emphasize what he perceives as risks to infrastructure brought about by detailed maps that anyone can browse: "[I]f highly detailed images become available, criminals could create more complete schematic maps of the power and water grids in the United States. With the vast amount of infrastructure across the country, it would be impossible to secure every location."
