Bingo. If one is going to invest some time to learn more, they were disseminating leaflets calling for the attacks on law enforcement and were assembling an explosive device with the goal to blow by the real building.
Minecraft on their devices is totally unrelated to the charges, but the media has turned it into propaganda and you don’t need to know it.
Complete BS on your part. The "explosive device" that they made were pyrotechnics and they threw some molotovs against a wall. The "disseminating leaflets calling for the attacks on law enforcement" were political leaflets that included slogans such as “the FSB is the main terrorist" that they hung on the local FSB office.
Police state-they sentenced Uvarov to five years in a penal colony.
