Nobody gets killed because of the 'human rights'.
Defending the 'human rights' in Russia is a very profitable business. They only kill for money here.

It may look like there are politically motivated murders in Russia but in reality all these murders don't bring any benefits to the 'bloody Kremlin'. Quite the opposite - in the eyes of the western press they become even more bloody and talks about human rights violations receive additional momentum.
It is simply not in the interest of the officials (of any level) to kill someone.
The activity of such 'strugglers' are only noted outside Russia. Nobody here takes them seriously, neither people nor the government.
I'm not saying that we don't have problems with the 'human rights' here, but the government positions are very strong and secure due to the abundance of idiots in the population and no human rights activist can harm them in any way no matter they would say, write or show.
But, from the other hand, if such an activist gets suddenly killed then it will be possible to spin the Western media with anti-Russian innuendo.
I ask then WHO GAINS FROM THE CRIME?
