It’s protest, some of it lawful, some of it crossing into unlawful riot. Throwing the term ‘terrorism’ around willy-nilly doesn’t make it so.
You may be unaware, but France’s Algerian diaspora goes back many decades. Algeria was a French colony until it won independence and there are a great many French Algerians with full French citizenship. Unfortunately, France has historically had prevalent racist attitudes to its Algerian community. While France has been happy to profit from cheaper diaspora or immigrant labour, full social and economic inclusion has eluded most of them, and they’ve seen disproportionate police violence. When this carries on long enough, the friction can get kinda hot.
This current expression of outrage, sparked by a police shooting of a young French Algerian man, will fade as authorities get it under control. Let’s not, in the meantime, pretend it’s something it isn’t. There has been no threat to the lawful governance of the French state. There has been a single death- tragic, but only one. Breathlessly going to the most extreme interpretation of what this is doesn’t contribute to building a clearer picture at all.
