So a person would accidentally take a photo of a sniper, upload it on the internet for PhotoSynth to build a panorama out of, the Secret Service will then look at the panorama, spot the sniper, and take care of it. All of that will happen in several seconds. Seriously? There definitely is a case for using technology for protecting VIPs, but it would be smarter for the Secret Service to just get several high-res infrared cameras and hook them to computers analyzing the images for irregularities (ie. "there's a person on the window of that supposedly empty building").
