Our media don't even need the government for playing down any Islam-related incident. They do this out of self-inflicted political correctness, because one cannot be a major player if one don't incense multi-culturalism.
That being said, there are 2 issues there. Is the Arab population increasing in Europe ? Yes, certainly - one just has to look at demographic figures to be convinced - and the same is true for most 1st-world countries. Is radical Islamism taking control (or already in charge) ? No, it isn't.
