You see mass rapes in Moscow on NYE by mulsim's ? lno why is that, cause its different.
If I'm not mistaken Russia holds number 1 in something like "correlation between found people and disapearred people". It's like police finds less than 10 % that disappeares in Russia yearly. And it seems like criminals kidnaps boys and girls to force them to became prostitutes in Caucasus Muslim regions or in Turkey (according to TV programms).
Plus, from what I understand difference between Russia and Europe -- in Europe they go to prison while in Russia not always.
For example, there was a story that guy from Tajikistan rented a room in an apartment where young girl and her grandmother lived and he had sex with the girl. Guy said that he was 14 years old and girl were 10 years old and she gave a birth to their daughter at age 11. Then police found out that guy was 18 years old and some time ago (before the story with girl) he was deported from Russia for some offenses and this time he entered Russia under passport of his younger brother. To make long story short he received suspended sentence and Russian passport in the end. He was represented in court by this guy
https://en.wikipedia.org/wiki/Pavel_Astakhov And that story was on national Russian TV but the guy was presented as some sort of Romeo. Also I think guy beat both young girl and her grandmother.
Also you can find a story in Russian media how car thief (or retired car thief) was kidnapped by Ramzan Kadyrov's bodyguards in Moscow and beaten and raped with cue stick. And they was freed after that.
Or there was a story when antifa skinhead Dimitriy Prahov hit a Dagestani guy with a knife and he died later (group of 4 Dagestani guys were beating 2 Prahov's friends or guys that he know, and this friends were a guys below 18 y. o.). Prahov said that he acted in self-defense but court wasn't convinced and he received 9 years. And from what you can find on Internet looks like judge may be bribed by Dagestani guys.
And about Tajikistan and others ex-Soviet-"stans". There was protest in Russia years ago, they wanted Russian authority to cancel "visa-free regime" (not sure how you call this in English) with Tajikistan and other such countries. Because aside from heroin traffickers, illegal immigrants and criminals there is nothing comes to Russia from this countries. I remember couple of years ago nationalists from St.-Petersburg posted that immigrants opened there Muslim-only brothels. Like, only Muslim girls only for Muslim guys. And almost everyday in news -- murder, rape, robbery performed by illegal immigrant from another -stan.
And if I'm not mistaken, I'm looked at Wiki some ago for info about Muslims -- in Russia Muslims is around 9 % of population. If I remember correctly in countries like France Muslims is only around 4 % of population.
Oh, and there was story at bloodyelbow.com how mma fighter from Tajikistan traveled to Russia to work and got recruited by ISIS.
