The Earth Liberation Front is suspected of setting fire to luxury homes near Seattle (KING-TV, Seattle)
SEATTLE – Police suspect an environmental terrorist group is behind the burning of five luxury homes in a model "Street of Dreams" development northeast of Seattle this morning.
A message signed by ELF was left at the scene, north of Woodinville, according to Snohomish County District Seven Chief Rick Eastman in a report by local KING-TV.
The Woodinville homes, according to a homebuilder who served as a judge in last summer's Street of Dreams show, used "Built Green" standards such as water-pervious sidewalks, super-insulated walls and windows and products made with recycled materials, the Post-Intelligencer reported. Advertising emphasized the environmentally friendly aspects of the homes, which were smaller than some featured in previous years.
Firefighters were not allowed near the homes, officials said, for fear of booby traps. Eastman said the blazes, which began at about 4 a.m. local time, were set at six houses. Three have been completely destroyed and two others seriously damaged.

I wonder what the ecological damage results from burning houses to the ground?
