Eastern Promises was a pretty decent flick that vaguely covered the meaning of some of the common russian mafia tattoos. Nothing like the documentary you mentioned but a decent show nonetheless.

* Right arm: Cathedral with five domes: symbolizes five years of imprisonment. * Shoulders: Stars: Symbolize a “career criminal” or Vor v Zakone in Russian (English translation: thief in law). * Right shoulder: cobweb: Aleksander did not explain its meaning other than saying that contrary to what has been suggested by some, it does not have anything to do with the Mafiya. In Russian prisons, tattoos using this symbol typically denote drug addiction. * Left shoulder: Russian script. * Left forearm: Half cat’s head, half skull: "Homo homini lupus est." Translated: Man is a wolf to his fellow-man. * Back: Grim Reaper holding a baby. * Back: “Gott Mit Uns”, meaning "God is with us" in German: for Aleksander, it’s a symbol of revival. This tattoo caused a controversy, since this slogan was written on belt buckles of German soldiers in the Second and Third Reich. * Knees: Stars: symbolize that the owner will never be brought to his knees. These tattoos also stirred up controversy, after a picture published on his website revealed a swastika in the middle.[6] * Pirate tattoo: stands for article 167 of Russian Criminal Code: "armed robbery". * "Fortis fortuna adiuvat" Translated: Fortune favors the bold. * A name on his lower abs (Maybe ‘Marina’). Later covered by a tribal tattoo. * A spider web on scalp.

You can see all of his tattoos here.

it’s safe to say that he’s a drug-addicted, career criminal nazi in the Russian mafia who views other people as his prey?

ummm..
