Re: tin foil hat
When Gary McKinnon was searching for UFOs he was not the only one digging through US government computers. What made him special was lack of precautions to hide his identity combined with living in a country with an embarrassing extradition treaty with the US. At the time, US security was to make an example of the few people they could get at to deter the ones who were completely safe in China and Russia (or at least appeared to be there).
Actually changing default passwords, deleting accounts of people who had left or wondering why the same person was logged in multiple times from different IP addresses was all a bit technical.
