The assailant is affiliated with Casuals of Belgium, an agglomeration of self-described soccer “hooligans” who have agreed to set aside their petty team loyalties and unite to fight Islamic encroachment in this tiny and culturally fractured nation.
Here’s the stony face of the assailant—who has been dubbed the “Hero of Belgium”—as he leads likeminded nationalists to the Stock Exchange in Brussels. They were marching toward an Easter Sunday vigil commemorating the more than thirty people who were killed and the three hundred or so who were injured during jihadist nail-bomb blasts at a Brussels airport and metro station on March 22.
And here’s his snarling face after he decked the Red Whale.
Compare his mug to the chinless goobery beta visages of Belgian Prime Minister Charles Michel and socialist Brussels Mayor Yvan Mayeur. Both Michel and Mayeur loudly condemned the casuals’ appearance at the memorial vigil—perhaps more loudly than they criticized the Islamic bombers who ripped apart their capital city.
