Repræsentanten for City of London Police gjorde f.eks. opmærksom på, at der til stadighed er vanskeligheder i forbindelse med samarbejdet mellem justitsmyndighederne landene imellem, fordi det, der i Storbritannien er en kriminel handling i forbindelse med hvidvaskning af penge, f.eks. ved gensidige pengetransaktioner med andre medlemslande, ikke nødvendigvis også kan indordnes under hvidvaskning af penge i disse lande, og at dette derfor konstant giver anledning til samarbejdsproblemer.
The representative of the City of London Police, for instance, pointed out that constant difficulties arise in the cooperation between the various countries' judicial authorities because cases which constitute a criminal offence of money-laundering in the United Kingdom, for instance involving reciprocal financial transactions with other Member States, cannot necessarily be considered a money-laundering offence in those states, which leads to constant problems in terms of cooperation.
