RowdyRudy,
I'd just like to state a few things here.
As a few Members here that are Fire-fighters from the US and beyond, would agree, you don't become a Fire Marshall over-night and I would be looking to the Court to prove the qualifications of the said Fire Marshall, before the case took place.
I've been in a Court room situation before as an Officer here and I would not wish it on my worst enemy.
Another point is, do you believe everything that you read in the paper or see on TV?
Another point, Fire investigation is left to those that know something about the science and the physics of this subject, we are talking the means to a conclusion.
This is the real world, not "Murder She Wrote"!.
