the 'Guardia di Finanza' has a long standing tradition of trying to extort money without regards to actual laws. its not long ago that they told all companies 'if you pay X% more than your tax report says you own then we won't destroy your company'. more recently they went after the Agnelli family trying to extort money without having an actual case.
its not the rule of law, its simply Might makes Right or modern robber knights...
