Here we go again.
If someone was to ask me my reaction to this I would say it was to be expected. There are many variables to be entertained as to predicting these events and there will always be those that allude to the immigration factor that we all know about in Europe at the moment. But it seems that the probability that French nationals are involved in these acts is a possibility puts paid to that idea.
There is also the idea that different cultures can produce this effect and this is a real consideration that needs to be taken into account but there’s always other factors at play. This in no way distracts from the facts of the case as that would be logically void.
All throughout history you can observe this layout and the particulars provide the detail that needs to be dealt with. I wonder how the authorities and public will engage a solution and deal with this problem and what side effects will occur. There’s always that to consider, if even in hindsight.
