Some of them have already figured out that's what's happening. Ever wonder why the shill presence has been ramping up steadily the last few weeks?
Well, release at least. Declass has already been ordered, and given to necessary parties (trial lawyers, judges, etc.), just not us for the reason you cite.
Firefighters make stands at houses, plus the burning trees themselves actually cool the fire because of all the moisture they release which acts as a preventative effect. There are plenty of fire locations around here that didn't turn out the same way.
