what the web master of silk road did was he put his site on this tour browser. what tour does, it balances communications through a whole bunch of different servers so that you can't trace who is using the site at any one child, can't trace who is doing the transactions. if someone is selling something on the black market and someone is buying it, you don't know who the two parties are. >> how is the fbi able to infiltration the server to connect the dots? >> the fbi did a really interest thing. they used some very, very traditional crime fighting methods that they always used, things like stings and confidential informants but they also appeared to have done, experts believe that they at some point hacked into the system. they understand how tour works and understand how the website worked and what they did was go into the website's own coding system and find weaknesses.
