The videos of what appear to be live lines on the ground writhing and sparking may tend to complicate this defense. I wonder how many hacked up "home power" systems might've been backfeeding into power lines? Could the electric company have actually shut of their feeders and still failed to de-energize big portions of the grid? Do people with local power there manage their own transfer switches or is that power company property marked "don't touch"?
