Political assassinations in Russia are usually done in secret.
When our own state department says 'Putin has nothing to gain by doing this' you know it's likely they don't want anything revealed they might have had a hand in either....since like Poroshenko...Nemtsov was one of our guys
The whole thing is just too "Messy" so no doubt hired armatures...interesting too the gal with Nemtsov said to be also dating a Ukrainian Commander....and the plots thicken...
Here's 'our' next guy waiting in the wings to assume control when Putins done.... oil tycoon "Mikhail Khodorkovsky" who is funding and assisting the on the ground activists to oppose Putin.....though he controls things outside of Russia now.
Here on the right, with Ukraine Pres. Poroshenko....you really can't seperate Ukraine and Russian politicians....these Oligarchs play their own games for political power and control of revenues and oppose one another...high stakes poker all the time...
And here he is sitting behind the pillar with Putin;s team Putin before he was tossed to the curb
