Many groups went extinct, but it doesn't mean that Russian OC is weakened. It's just that most of these groups went into legal business. And other groups were brought down by authorities or killed by other groups. They still hold enough power.

The Russian OC leaders and guys who started in the 90's now are sitting in the offices. While guys at the age of 20 are doing the dirty job.

It's more or less that it's not anymore so public and criminals have became smarter.
