0WaitState writes "A judge Tuesday ordered a former city worker who locked San Francisco out of its main computer network for 12 days in 2008 to pay nearly $1.5 million in restitution, prosecutors said.' Keep in mind the network never went down and no user services were denied, and given that Terry Childs was the only one who had admin access (for years prior) it is difficult to understand how they came up in $1.5 million in costs, unless they're billing Terry Childs for the City's own failure to set up division of responsibility and standby emergency access procedures?"
We warn the reader in advance that the proof presented here depends on a
clever but highly unmotivated trick.
