Colonialism comes back to bite in the butt.
The perpetrator was not from a former French colony.
From wikipedia:
The perpetrator, Abdoullakh Abouyedovich Anzorov, was an 18-year-old Russian immigrant of Chechen ethnic descent, born in Moscow.[27][28] Chechnya is a Muslim-majority republic and federal subject of the Russian Federation.[29]
Anzorov had come to France with refugee status 12 years earlier as a six-year-old boy.[7][30] He lived in the Madeleine district of the Normandy town of Évreux, about 100 km (62 miles) from the murder scene, and had no apparent connection with the teacher or the school.[31][32]
The Anzorov family came from the village of Shalazhi in Chechnya. Abdoullakh’s father Abuezid moved first to Moscow, and then to Paris. Anzorov’s half-sister joined ISIS in Syria in 2014.[33][34] In March 2020, the family had received refugee status and 10-year residency cards in France.[6][3] Abdoullakh was not noticed by security agencies, though he had previously been in courts on minor misdemeanour charges
