"I live in Morocco and I know that since Germany opened its borders to Syrian refugees, more and more young Moroccan men have been leaving the country. It is easy to fly to Turkey - Moroccans don't need visas as they do for most countries - and from there they join the genuine refugees from Syria. When they reach Greece, they are initially treated as refugees, but now they are more likely to be thrown out of the refugee camps. That doesn't discourage them, they go on looking for other ways to western Europe."
Morocco (and Algeria) are looking more and more like a smoking gun in this whole mess.
The Economist discussed demographic makeup and focused on the fact that the tilting towards young single men is not that pronounced among the Syrians, but is huge among the Moroccans and Algerians.The very high crime arrest rates, similarly, are being seen mainly among the Moroccans and Algerians--the Syrian men seem to be a lot less of an issue.
We need some proper investigation of what is going on here, as the PP said.
Months ago, some people did try to discuss or comment on this sort of issue ("There seem to be a lot of young men, most of the people don't actually seem to be Syrians" etc. etc.) but their comments, even when expressed in non-inflammatory language, were immediately shut down amidst accusations of racism and being a heartless person. So of course this was not properly looked into.
