Only a conspiracy nutter would believe Putin was directly involved in this.
Same for CIA direct involvement etc.
Do you understand word "indirectly" in at least two of my posts in this thread? I am pretty sure Putin didn't want Nemtzov dead - he was indeed too insignificant and posed no threat to regime.
But anti-Western Goebells-level state propaganda boosted destructive powers of already agressive Russian society. Enormous hate of ultra-nationalist, neo-fascist and neo-communist Russians will be spilled on political dissidents and just any opponent now.
For many years Nemtzov was classified as enemy of the Great Russia and USA agent by them. Now he is dead, killed right near Kremlin.
P.S. Just one minute from your average Russian TV program by D. Kiselev, for your typical Russki sheeple: "We are only nation on Earth capable of turning USA in radioactive trash":https://www.youtube.com/watch?v=EkMT_oLempE
Deal with it now. 90 % of their state owned TV is like this for last year.
