Do you really think that they thought that the power company would stop putting up electrical towers because they tore one down?
Or that all lumber companies would start selling planet-friendly coffee because they torched one in Glendale?
....How do you know they did it to intimidate?....
Terrorism is intimidation.
Acts of terrorism are committed to intimidate and gain a goal. The goal in the mind of a ecowhackjob can be any kooky thing that comes to mind.
I wonder if any of these perps live in anything but mud houses, use electricity in their daily lives, or drive around anything but a bicycle?!
