I lived in The Hague for 6 years (mid 90ties). It's a village with quite a few cultures. The only issues I encountered were with the Muslim population. Aggressive, inpolite, take every reason to bring violence and terror when they group together. Then I lived another 5 years in the east of the Netherlands. Here there is much less mixture of cultures but the group that caused the problems in this region as well were the Muslim population. Let me say Muslim men.
Meet one on the street, you can have a talk without problem and you think, that was actually a very nice man. See him a few days later with another group of Muslim men and they behave like an aggressive herd who think they have every right to make clear to you that you disgust them, that you don't belong in their world.
There was quite a lot of effort made within Dutch culture to make them feel welcome and respected but it seems that it only worked in one direction. Yes the Dutch respect our beliefs, religion and culture but we don't respect theirs!
Now I won't say that they are facts, they are experiences I have made and this combined with population presented in crimerates and the news comming out almost every day on Islam just confirms the experiences I had. So my opinion will be much more based on a negative view for this religion and the people who practice it.

Toulouse is becomming a problem as well, which once again confirms my thoughts!
So then it is up to me not to generalize for the whole Muslim population, but that is not always easy when almost everytime my negative view on Islam or the Muslim population gets confirmed.
I can read in hundred books that Islam is violence and I can read in hundred books that Islam is peace. I can bring in 10 points why Islam is violent, another person will come in here and give another 10 points that show complete the opposite.
For me, the negative view on this religion gets confirmed everytime and the actions of IS and the situation in the south of my country don't really help.
