An anonymous reader writes "Photographers from a Canadian company are going house to house, shooting pictures of every house in America, in hopes of building a giant database that can be sold to banks, insurance companies, and appraisal firms. While this activity is legal (as long as the photographers don't trespass on private property to get their shots), there are obviously concerns about security and privacy. Considering that an individual can be detained and questioned by the FBI for photographing a bridge in this country, why should this Canadian company get a free pass? Tinfoil hat aside, something seems very, very fishy here." From the Arizona Star article about the photographing of Tucson: "'The [handout given to people who complain] made it sound like they're doing it for law enforcement, when in reality they're doing it for sales and marketing,' said [a City Council aide], who received several calls about the company."
