I thought (inspired by Person of Interest TV show and photo supersaturation) after the Boston bombing it would be a good project to use publicly available photos, video, security camera video to track or search for suspects. Or it could be used to search for a kid such as during an Amber Alert. But I have no skills to do this :(
