John,
I concede you are right, I was wrong.
However, with not having been "on-scene" I can only go by a few photo's.
Usually as a Fire Safety Officer I was part of the local Fire Brigade Operational Staff anyway.
So I would be in attendance at any fire like this.
It lets you see how well the structure is burning and where it is burning from and the colour of the flames.
Once you get down and sift through the remains of a building, you've lost most of your forensic evidence.
