Very hard. In general, data on this and similar issues comes from multiple sources, some of which include official crime statistics countries report to various international organizations such as Europol, Interpol, UNOCD etc. Depending on the editor/user of data, some will be evaluated and supplemented by other sources - for example drug exports from and drug imports into etc/arrest statistics/cross border data for immigration offenses and others.
