I am toying with the idea of creating a website where people can report suspicious objects by clicking a picture. Once uploaded to the website and geolocated (via an App), the location could be flagged on a Google Map, so others can avoid it. If enough people report the object, the website could automatically dial local authorities (perhaps each city should have one). It's kinda "surveillance for the people, by the people", especially in areas where government surveillance isn't adequate. It would harness the power of technology and the masses to improve public vigilance, warn other people in the area, in real time. There are privacy implications, and there's probably a huge scope for misuse, but it would save lives. What do people think?"
