I get it, the dichotomy aspect; it's like if someone breaks into my home, the police tell me to get screwed, or shoot back(had it happen); where as someone shoplifting at Wal-Mart, will have the full force of the police, charged, and prosecuted.

So yeah, I get the comparison. I don't know what happened at Notre Dame, but I find it funny how fast somethings can be swept under the rug. Take into account of the warnings that ISIS, or other terrorists were targeting such structures, and it certainly leaves some questions when considering how fast a cause was determined.

It would be interesting to know what insurance was on the building, and was it properly insured, over insured, or what?

Just because it's 850 years old, doesn't mean it's 'solid', and it may of had an expensive repair needed; beyond the scope of projected work.

If it was an electrical fire, photographic proof of that, shouldn't be too difficult. I've personally seen entire mechanical rooms melt into a 3" layer of steel across the floor due to cut-outs not opening as designed..... So even to state 'electrical', and let's say it is, that still doesn't rule out intentionally set; insurance coverage is where I would look; also any issues that may of gone somewhat unreported.
