[11th Commandment]

I doubt the trail balloon theory. This was a successful attack. If these guys wanted to take down the grid it looks like they could have done it. Why tip-off authorities to future attacks.

My suspicion is eco-terrorist.

If indeed it is a terrorist, perhaps they were attempting to evaluate just how much havoc this would wreak with emergency response systems so they could judge its multiplicative effects when used concomitantly with future attacks against other higher value targets?
