OK, that is interesting.
I was keeping track of the wave of car bombings on the mexican border a little over a year ago. There was commentary in the MSM about how they were identical to ME car bombings. There were about four or perhaps five in a row. They started right out of the blue, then they stopped like flipping a switch.
Looking at the photos, http://www.valleycentral.com/news/story.aspx?id=758095#.T8BPaDkzauI this one does not appear to be the “professional” level seen in the attacks from over a year ago.
This is somebody new, an amateur.
I'm not aware of any car bombings in Maine.
