This appears to have been a murder based primarily on an attempt to extort money from people who were seen as being in a position to pay-off the kidnappers, rather than race hate aas such. That doesn't make it any less disgusting, but the distinction is worth noting.

Next time it could be some relative of a rich Arab, or a footballer, or just about anybody believed to have access to money.

And it could happen in any country, nothing particularly French about it. And the criminals concerned could come from any background.
