  It's technically infeasible to locate someone via CCTV unless you have an accurate location already, for precisely this reason - there's a massive surfeit of data to search through, and current facial-recognition software is incapable of the task.

    Sure, but the case here was "we have the IP address, we want to know who was behind it", which is certainly feasible.
