They’ll send in a drone and blame it on a “gas explosion”, ammo “stockpile” going up, whatever. With the BATFE investigating the ruins, “no evidence exists” to prove anything but the party line. In OK City and at Waco, the sites (scenes of the crime) couldn’t be destroyed fast enough for those guys.
They’re welcome to try whatever they wish as long as they know beforehand that they’ll have to live with the consequences.
you are right. Now that I recall, that is how they did it at Waco. Put in the gas and started the fire and then accused Koresh of burning the place down. and Immediately cleaned the scene.
