The documents obtained by the RT crew can help to bring us closer to understanding how Daesh governed the people on the territories they seized.
There was a system of fines for every minor misbehaviour.
Personal dossiers on prisoners and those executed, financial records of paid fines only prove how orderly the jihadists were in maintaining records.
Amongst the documents they discovered are receipts of the relatives who bought the release of family members who had been subjected to punishment.
The papers also reveal that the age of those punished was as young as 16.
This young man, it says, was executed for the murder of his aunt.
There are also documents certifying that citizens had to obtain special permission to move from one district into another.
One of the records, fixed with a seal, is the appeal of an elderly man who explains that he is too old to live alone and asks for permission to move into a neighboring district to join his daughter and her family.
Another man appealed for permission to move for three days to another district to work temporarily at an oil field.
The jihadist group commanders turn out to be very scrupulous in bringing up youngsters whom they have recruited into their ranks.
An applicant for a position teaching future fighters had to undergo an examination; however the questions posed have nothing to do with general education.
The criteria for being selected, as one of the documents reveals, depends on how an applicant answers to the following question: how would you perceive a person who brings food to a Christian who has been put under house arrest?
The right answer, according to the test, is that this is a minor breach of faith, as this person loves his friend more than he loves Allah.
Another question asks for a definition of democracy, and what punishment is appropriate for a person who sympathizes with democracy.
Among the documents is one where knowledge Sharia law was estimated as a percentage, just like a report card in a western school. Across each name there is a mark and a resolution whether the applicant can be allowed to teach or whether he or she should be sent for additional training.
The full documentary is set to be aired on RTD in about a month.
