That's fine but how do you deal with the second and third generation immigrants that are being radicalised and committing these atrocities? London attacks for example were home grown. The people that were born in our countries need to be integrated properly otherwise these young men will continue to be radicalised and strap on suicide belts because they don't see a future for themselves inside their own countries.
The situation is a it is. The UK should never have allowed Muslims settle in the country after WWII, France and Germany the same. Now they are here, and they've had children and grandchildren and they still live in immigrant ghettos in Paris where no job and no future used to lead to riots. Now it is turning to something easy more sinister.
Twenty years ago I worked in the south of France. One of my work colleagues was a part time policeman and I have never met a more institutionalised racist in my entire life. I witnessed this 40 year old well built man beat the shit out of a 16 year old black kid because he could. It made me sick and nobody batted an eyelid when he did so. I also witnessed the same man walk away from the scene of a car accident because "she'll live and I'm off duty". He was just a cunt.
Germany is currently in the must of the NSU scandal where it appears to suggest that members of the police and security services had whip rounds to raise money for right wing neo Nazis groups, and parties with some of them that went on to shot innocent Turkish people over a period of many years.
We can't continue with half measures. We should close Europe's borders. We need to closely review who has arrived as a refugee and deeper anyone that has a dubious background. Check out EU militia watch on twitter. Everyone else who is here in Europe or born here needs to be included in our societies over and for all. We need to have the "grey zone" on our side once and for all. They need to be rating out these radicals and not hiding them in their hidden societies. But let's not forget. It is our fear and bigotry and racism that has created these ghettoes in the first place.
