The "cab" analogy breaks down because the cab driver kinda remembers who 
you are, while packets only carry a pair of addresses. But yes, 
detective work included finding cabs who had picked a passenger at some 
location, and asking the driver where they went, or vice versa. And that 
can be broken by picking a cab for a random point about midway to your 
destination, then walk a block or two to scramble the search, then pick 
another cab to your actual destination. Kind of like using VPNs.
