"On Friday night, a local lawmaker left his home in the north Russian city of Pskov and was attacked from behind by three men. He was beaten unconscious, only to wake up, bloodied, in a hospital hours later. The lawmaker, Lev Shlosberg, had been leading an investigation into the mysterious burials of several members of the Pskov-based 76th Airborne Division who were rumored to have died fighting in Ukraine. Journalists who attempted to reach the cemetery days earlier were also attacked." Source: http://www.buzzfeed.com/miriamelder/vladimir-putin-isnt-going-to-stop#48gn400
The big difference is that Putin has nuclear weapons and was not afraid to threaten Ukraine with them if they don't stop resisting.
"Kiev has received threats of nuclear retaliation from Russia through unofficial channels if it continues to fight pro-Russian separatists in eastern Ukraine, the Ukrainian Minister of Defence, Valeriy Heletey, announced on his Facebook page on Monday."

A few days ago there was an incident with the plane of the Russian Defence Minister who did not file the correct flight documents to fly over Poland from Slovakia and was subsequently temporarily denied entry into Polish airspace. Well, we did not need to wait long. This is a video made by one of the Russians fighting in Ukraine - Arsen Pavlov aka "Motorola". He says "If you don't want to let Russian Federation defence minister through Poland, Motorola will come to you"... watch till the end to see what he means: https://www.youtube.com/watch?v=B4zTM8FvJR4
This is not a joke. Russians lived under Soviet propaganda since 1917 to 1989, then had about 10 years of relative freedom under Gorbachev and Yeltsin and started falling into tyranny again under Putin since 1999. Russians, contrary to Germans, never acknowledged that they were the bad guys during World War II: they attacked Poland, Lithuania, Estonia, Latvia, and Finland, but they still have monuments to Stalin and proudly display the hammer and sickle of the Soviet Union.
Propaganda works like advertisements, you may think that you are immune, but you are not. If you listen to it often enough, it soaks in. What propaganda can do to people? Let me give you an example from a book I am reading now: "Savage Continent" by Keith Lowe. On page 29, he describes the fate of displaced persons in Germany after the war:
"[...] as Poles, [they] were even blamed for starting the war and bringing this whole misfortune upon Germany". This is exactly what Russia is doing now: blaming Ukraine for civilian deaths in Ukraine where Russian-sponsored and Russian forces are fighting Ukrainian forces. There would be no civilian deaths if Putin did not want parts of Ukraine for himself.
