"The Looney Tunes Killer strikes again!"
No, all violence in Luxembourg doesn't have to meet a mandatory silliness minimum -- the mallet was supposed to make his death look like an accident, like the elderly septuagenarian had fallen and cracked his head open. On ... a ... rubber mallet.
But after being bashed seven times in the head, Glock managed to wrestle the hammer away from the hitman/pro-wrestler, punched him in the eye, knocked out several of his teeth, and rendered him unconscious. Ewert had already run away like a coward at that point, which isn't a judgment call on our part: Ewert himself described the situation by saying "I am a coward."
At least he has some self-awareness.
The physical fight was over, but Glock wasn't done. Even though he had lost a liter of blood, he kept his composure, and the first thing he did after getting to the hospital was take his assets out Ewert's hands. Luxembourg gave Ewert and the hitman 20-year and 17-year sentences, respectively, for attempted murder. And a round of reluctant applause for the most hilarious assassination attempt this side of Cuba.
