I am not making claims about "any sense of order", but going by what I read European police lost control of some chunks of its territory.

Take Calais. Here is a sympathetic account which is actually a kinda-detective story: a body in a wetsuit washes up on Norway's shore and people are trying to figure out who-what-why. The clues lead to an immigrant camp in Calais and, well, it's pretty clear that the French state lost control there.
