Criminal Tattoo

Whilst in Sweden (Gothenburg in particular), I noticed an extraordinarily high number of young people sporting extensive tattoos covering entire arms and legs... and also numerous exhibiting neck tattoos. I wonder, are young Swedes more heavily tattoo'ed than their American, British, French, Chinese, Japanese, or Australian counterparts? Or is it mainly a Gothenburg thing - all the heavy tattooing? 

Aesthetically, I saw a great many tattoos with Asian or Metal inspired symbols and themes - particularly on the armbands and sleeves. One wonders if a lot of the Asian ink is inspired by Japanese tattoo? Incidentally, there is an exhibition of Japanese Tattoo in Gothenburg at the moment. 

I didn't notice any at all inspired by Russian Criminal Tattoo however... I think this is an aesthetic space that has been a little overlooked as a source of inspiration. I came across an encyclopaedia of Russian criminal tattoo recently (Russian Criminal Tattoo), and I must say a lot of it really is rather stylish and very original. I'd like to get the book, and more, I'd like to see some criminally inspired ink...
