Yeah, Chechens are very violent. All these Hachi* groups are violent and they kind of have their own laws to deal with stuff. If you look at Russian Groups they more or less nowdays tend to put the approach in a more civilized manner like the Cosa Nostra with sitdowns. But still usually these sitdowns end with one part being the loosers and then eventually someone gets killed.

In Chechenya/Dagestan and that region down there in the map, I've heard people say it's still the 90's. Terrorist rebels aren't the only groups ruling the game there. There's also criminal groups that control their areas, extortion, murder, robbery and general crime happens there.

I for fact know that in Latvia there's also a Chechen criminal group which is very large and very thight-knit organized. But they weren't let to do criminal activities in the capital city Riga in the 90's, they were forced out of the city by the local Russian groups.

*Hachi - Middle Asians/Caucasians/Churki in Russia.
