Yes, this is very disturbing, but it is happening all over the world. It now seems that some youth, especially if they are involved in gangs, think it is much "cooler", and certainly much easier, to resovle a dispute or a "disrespect", with a gun rather than with their fists or just "talking it out". It's unfortunate, but that is part of our current reality. I do hope that both the Dutch police and French gendarmes are able to keep a lid on it, or eventually tourism may suffer.

And I don't think it has anything to do with whether guns are or aren't allowed. The statistics clearly show that the incidence of gun violence is generally even higher where guns are more readly available. So while the guns are an exacerbating factor, I don't think that is the root cause of the violence.
