There were several moslem terrorists on the construction crew, doing menial tasks, who brought-in accelerants and remote igniters, so that when they all pulled-off the job for Easter Week, they could detonate with a cellphone.

I would tend to agree with this hypothesis. Muslim workers everywhere, infiltrating work crews. They don't like Christian artifacts and want nothing more than to erase it all. It's got to be sabotage by Muslims. French government is too stupid to save their French culture and will lose it all.
