Vlastos and Angelopoulos are bad dudes. But here are many more. Many much bigger that attract less attention. Above everything Greek OC (from Greece) tries to pass themselves off as legit "businessmen" and attract as little attention as possible.

We have ppl involved in fuel/oil smuggling that are literally billionaires now.

For ex:

https://en.wikipedia.org/wiki/Dimitris_Melissanidis

http://research.omicsgroup.org/index.php/List_of_Greeks_by_net_worth

Started out smuggling fuel to Serbia during the war when there was an embargo.

Estimated net worth of 3.4 billion now. World's largest independent supplier of fuel. Contracts with the US navy to refuel their warships world wide.

And he STILL smuggles fuel (or so all the rumours say). VERY serious guy who doesn't joke around.

Greek OC doesn't worry about supplying drugs to neighbourhoods or having ppl on street corners. Of course there are ppl that do this, but they are small fish.
