Organised crimes - development

Since school, organised crimes have been part of every culture where there is presence of man. For man likes to gather in groups for protection, support and wealth.
It is interesting to see how many groups of the organised crimes are there out in the world. As far as I remember,  there is Yakuza in Japan, Mafia in Italy, Mafia in Sicily, Russian Mafia, Irish Mob, Cosa Nostra in US and Chinese triads.
In fact, they showed us how globalisation is possible with their transnational crimes. The logic goes if they are able to sell homegrown vices in other countries, why not normal product and services?
I chanced upon this interesting map which piqued my interest in organised crimes once again. Follow the link in the blog title and you will see it.
