The video is from April 2013 - the destruction of Saint-Jacques’ church in the north of France started at 13 Feb that year.
According to Churches at Risk, Some French Considerations:
Some unfortunate famous cases are Saint-Blaise’s church, where the vault collapsed in 1998 and had not been repaired ever since or Saint-Jacques’ church in the north of France, where it has been years since walls are covered by cracks, weakening the entire structure and opening it to rain penetration, and where the only remaining user of the church was a tree
La Croix provides a timeline of this specific church and what led to this building being demolished.
Built between 1868 and 1878, the church of Saint-James, in neo-Gothic style, survived two world wars and the bombings. But unstable soil, water infiltration and the storm of 2004 have undermined the building, which is collapsing in places. Religious services have not been celebrated there for twelve years. The walls are cracked, the windows caved in, a birch grows on the buttresses.
At the start of the month, with the thaw, blocks of stone fell from the church. Immediately, the city council acted on a meaure of imminent peril, evacuated the neighborhood and forbade access to the next-door school. An expert was sent urgently. In the wake of this, some machines "made safe" the building, by collapsing the choir.
The priest does not question the decision of the town hall, but rather the method. For him, it is "a reality that's powerfully symbolic, loaded with history, which brought together the faithful for a century" which they are putting to the ground (a.k.a. "burying"). Instead of the religious building, the municipality wants to build a square and promises to "leave a trace of the church" . Father Brunel was not discouraged. In this destruction he sees "a true Lenten call to attach himself to Christ and to the living Church".
If the destruction of this church building was part of a "Muslim Conspiracy" or something along those lines, you would not expect one of the priests to be OK with it. It seems as if this church had just been unused for a long time, followed by it becoming structurally unsound and condemned.
