Here's a story about a program developed by the Swedish government that ended with biting them self in the behind.
I can't remember the month or year. The Swedish government wanted to help people in other countries, like Iran, North Korea a.s.o to surf on the INTERNET, without getting caught- So they developed TOR.
What the Swedish government wasn't aware of, was that this software program could fall into the hand of the wrong people
It did- yesterday I heard on the news that the police had hard time to track the criminals using this program.
It was however stated in this news issue, that not every one using TOR-was criminal.
It was told that peopled shared child porn using this program
Here's some information about this program
Sorry every info is in Swedish, can't find anything about it in English
It's some type of program hiding a IP-address a.s.o
