It's like the Russian mafia, in a way.
Most people are unaware, but since the early 2000s, Russian murder rate has halved - and halved from what was a rampant state of perpetual mass murder.
This has to do with Russian organized crime "going legit", that is, they are still shooting people in the head, but they have learned to go to the top of each pyramid, and popped their way into construction, infrastructure, and other investment ventures.
