> The rebuilding is apparently going well, but this is hiding the fact that nobody seems to be doing any inquiry about why the fire wasn't stopped in time.

Is this a true statement? I remember reading an extremely detailed play-by-play in one of the major papers a couple years ago that did a pretty good analysis of why a confluence of factors led to the fire. I don't know what the status is of any governmental, official investigation, but I at least saw some thorough investigative reporting from news organizations.

I agree with the sibling comment that this feels a little like scapegoating. Like many disasters like this, it wasn't just one thing, but a confluence of lots of little innocuous things (e.g. new guy on the job, can't remember all the details but maybe there was a phone number change IIRC, etc.) that led to the fire. Not saying a thorough investigation isn't warranted, but pretending these types of things are completely preventable is also a mistake IMO.

Edit: This is from a US government website, and I can't see all the details but it looks like someone did do a root cause analysis, https://www.govevents.com/details/37273/risk-management-case... :

    In the days following the fire, questions began to arise about what could have caused the fire and, also about the nature and extent of the fire detection and protection systems. It turns out Notre Dame had one of the most sophisticated and elaborate fire safety systems ever designed, befitting a landmark of its stature. A team of experts had spent more than six years and untold funds developing the fire protection plan. Yet, when the system was put to a real test, it failed in spectacular fashion. How this could have happened, and what lessons can be learned from this tragic event with be discussed in detail.
