2: Exactly. I said it before. Nemcov was hardly a problem for Putin while alive. His "opposition", having discredited itself by plundering Russia in favour of the Americans during the 90s, hardly ad 0.5% of support. While dead, Nemcov has suddenly become a much bigger problem. One can try demonise Putin in many ways, but you can't call him stupid to do this... A stupid politician wouldn't have survived in the turbulent post-90s Russia and wouldn't have managed to bring back order and restore some of the destroyed economy.
Or he was aware about ... and let things happend ! Do not tell me that Secret service in Russia was not aware about as we know that everything is under strong audit .... phone, internet ....
Camera picture ? ... i am pretty sure they know who are already behind... we will find 3-4 simple guy linked to right wings or extreme party ... but who called to murder ? We will never knows as all past crime done in Russia ( mostly political & press murder ).
I still can not figure -> How police has been so slow to find 1 car .... ( not the white one ... this one is just to fool people .. ) but the dark one who deposit the killer ...
