Seen random news on building fires where they can pin point the cause of the fire somehow even though the building looks so charred and damaged there’s hardly anything left. How are they able to determine what caused the fire?

I’m a criminal defense attorney. And I’m going to say there’s a large amount of junk science to this. Yes, if you pour a bunch of gasoline around a building and set it on fire, they may be able to find traces of the gas. Sometimes there is chemical residue that can be collected.
But like drug dogs, there’s also a lot of “we have decided that these techniques work, and we have certified ourselves as being experts in this area”. There aren’t really a lot of double blind tests of these techniques by outside groups.
