Is per capita the right way to rank this? A camera covers an area. The same picture can have 1 person it or 10000 people in it. If you're the only person on a route, and I have one camera at a point on that route.. is that really the same as 100 people on a route, with 100 cameras along that same route? I would say not. In the 2nd instance, I've taken 100 pictures of you (and 99 other people), and know in more detail what you're doing. US and China have a similar land area.. so we can assume in China you're caught on camera more frequently. I say assume, because we don't know how much area these cameras on covering--which is the more important stat. There's a big difference between a wide area camera, and a security camera outside an entrance pointed at the ground.
