In order to leave less place for the possibility of arbitrariness in prisons, it is necessary to introduce total video surveillance within them.
Moreover, the head of the prison simultaneously with the duty officer of the prosecutor’s office should see the video image in order to react promptly to the recorded violations. In addition, records should be kept in an untouchable archive for several years.
This will discipline both convicts and guards.
This practice has long been used in developed countries.
It is foolishly not to use modern technical means to improve lives of the citizens in all spheres.
