What about non terrorist Islams?
What about fires started by neither?
What about welders? One fire recently was started by a spark from a welders grinder.
What about non Islamic non terrorist non welders? A fire in Arizona was started by a overheated pick-up truck. Neither a Muslim, nor a terrorist, nor a welder.
You get the drift.
Now, how about lightning?
A super firestorm burning along a 1,000 mile front would pull in hurricane force winds and race like a burning tsunami.
Get serious. The Trade Centers weren't brought down by a big draft and some snowballs.
If you live anywhere near trees and brush, this is a major concern.
