Sherlock Holmes would be proud!
The Germans have started recently talking about the amount of money in the drug distribution network, and the massive amount of money-laundering required. So the Lebanese gangs that get heavily into this...move their money back to Beirut, then flush it via Cyprus banks...back into fake companies and onto Germany...where they buy apartment buildings.
So they reinvested it into German property, and take the profits off the apartment buildings back to Lebanon a second time.
Long-term, they are set to make billions per year...just off the legit real estate game.
