When I was 16 years old, I started a 2600 meeting at a local mall food court. We joined in the 'Free Mitnick' movement, and would go around handing out flyers, explaining the implications of his case, peppering the place with stickers, putting them in copies of 2600 in Barnes & Noble and Borders. His case was an inspiration to a budding little hacker and taught me to become more idealistic and push for legal reforms and the rights of people who were punished far more than they deserved. Later in life I got to meet him at hacker conventions, and he was a super nice guy. I even got one of his lock-pick-set business cards! I know he's somewhat of a controversial figure, but he was also inspirational.
The authorities obsession with Mitnick was because John Markoff and the New York Times made the public believe that hackers were effectively in control of everything and could go as far as starting WW3 by hacking into NORAD and other similar caliber BS that never happened.
