Lately, beatings of prisoners have become commonplace. Those who are placed in solitary confinement or put on prison regime for offenses are beaten the most.
Prisoners who arrive at the colony from jail get a black bag put on their heads at the checkpoint. Handcuffed, they are taken to the second floor where officers beat them up.
All political prisoners are put on preventive records and treated more harshly than the rest. In particular, some are forced to sing the official state anthem, and they get beaten up for refusing to do so.
Convicts’ rights exist only formally, in practice they do not have any. The penal colony administration can deprive a convict of everything: mail, the right to appeal, meetings with relatives, a lawyer, etc., and neither the prosecutor’s office nor the court will side with the convict.
