Everyone knows that Russia is corrupt up to the top. How? Pretty much every top politician (and their families) in russia own far more than can be purchased on a state salary. Spokes person for Kremlin is spotted wearing 700,000 Euro watch when his official salary is less than 1/10 of that.
A lot of Russian government officials and their inner circles own multi-million dollar properties in: London, Spain, New York, Boston etc. Their families live in the west, their kids go to schools in usa and europe...
Panama papers disclose how these multi million bribes and shady dealings are accepted and how money is transferred and used to buy up assets overseas. Good old days of a bribe in a suitcase are gone... Its hard to fit $300mil of cash in a suitcase (well Italians would argue lol).
IT IS very suspicious that no high profile Americans were caught in this release... It is possible that USA players simply use different entities to set up shell corps and transfer money using different channels.
