I really really hoped I'd manage to get through the comments to this story without reading a pathetic Daily Mail style rant along the lines of your comment.
McKinnon did the US government a service by showing up lax security practices. Sure, he poked around fulfilling his LGM obsession, but they should be paying him a bounty rather than prosecuting him, and since he was in the UK when he committed these 'offences', he should be tried here and given an ASBO at worst.
Still, you're entitled to your view, however stupid it may be.
