In any other country, the perpetrators would have been lynched by now.
That would have happened in countries such as Russia and China, but not in the European Union. Open season has been declared against natives in the EU. The migrants can do whatever they want, and later they can avoid imprisonment by claiming that they are below the legal age.
I live in a European country and unfortunately this is true. Lately many of such incidents have multiplied and governments are trying to hide or mitigate them. If you are speaking against immigrants then you are considered a racist and generally you feel like as a foreigner in your country.
