I think paying the guy was a good idea just to get the camera back. Why haggle over $20? The cops drag their feet on stuff like this and I would do anything reasonable to get the camera back. I wouldn't pay the $20 as good will. I would do it to get the camera before it is sold to someone else or the seller disappears. Really the cops should have showed up at the sellers place in 24-48hrs and started getting to the bottom of things. This case was handed to them on a silver platter.
