Guys such cases are "single cases" so don't become racist and we have to be aware not to rise prejudgments against certain groups. It took the UK police also 20 years to arrest an Iman that support terrorism and is responsible to recruit members for ISIS but they are quite fast when it comes to terms of "hate speech". The media can spread one sided pictures of refugee kids with big eyes when most of them actual men but they can put an iron curtain on mass child rape my migrants. Divide and conquer, when you make it all look by mental individuals or "single incidents" you make it hard for people to unite against the enemy.
We will stand tall in the sunshine
With the truth upon our side
And if we have to go alone
We'll go alone with pride
For us, these conflicts can be resolved by appeal to the deeply ingrained higher principle embodied in the law, that individuals have the right (within defined limits) to choose how to live. But this Western notion of individualism and tolerance is by no means a conception in all cultures. - Theodore Dalrymple
