It depends on each countries, even inside the Eurozone it can get complex, for one of the European countries it is:
(1) Money laundering means:
1) the concealment or disguise of the true nature, source, location, disposition, movement, right of ownership or other rights related to property derived from criminal activity or property obtained instead of such property;
or
2) the conversion, transfer, acquisition, possession or use of property derived from criminal activity or property obtained instead of such property for the purpose of concealing or disguising the illicit origin of the property or of assisting a person who is involved in criminal activity to evade the legal consequences of his or her action
--
"the conversion, transfer, acquisition, possession or use of property derived from criminal activity" can be applied to a lot of situations.
Even a shop thief could be accused of money laundering.
Obviously it would be interesting to see how the judgment goes.
If there is any follow-up I'm very interested.
