As far as the Lebanese go in Berlin; I feel the Abou-Chakers (the family that has ties to the local rap industry through Bushido) is far from being the most feared or powerful. The Al Zein - Omeirat family has way more pull with branches throughout the whole of Germany as well as international connections. Drugs, extortion, weapons, organized robbery...the whole enchilada. That German series 4 Blocks kinda portrayed them as somewhat cartoonesk criminals that, despite the intimidation tactics, are opposed to murder. Far from the truth as they're definitely not shy to whack someone (the case of Zaki Al Zein for instance).
