These inevitable attacks by unassimilable cretins proves how dangerous liberals are when they have power. Merkel and the other clowns imported the thugs really believing the savages could be civilized. Unless Islam is destroyed as a political power these types of things will occur over and over again.
But liberals are congenitally unable to learn their lesson.
It would be one thing if it was a small, isolated portion of the world where these crimes were happening, but this is Europe. Liberals will destroy European civilization under the ruinous belief in multiculturalism and egalitarianism. They are as evil as the Islamic bacillus they've introduced to Europe.
