CLARK. I have often questioned quoting burning temperatures of accelerants it serves no purpose unless you factor in the variables.Fuel on its own will have its temperature but burning in the right enclosure with oxygen being forced in you would then have conditions similar to that of a furnace .As you rightly say all theories need consideration until proven to be false but in this case this is impossible , you have no crime scene and any evidence was sold to China a bit lively, its these actions that gave life to the many theories almost creating a kind of information smog obscuring and obstructing any viable investigation.
