His testimony focuses mostly on the looting of the police's secret service account which holds money used to pay informants, operate safe houses, purchase assets and cover the bills for covert operations.
"Documents are classified to hide the identity of agents as well as informants, not to divulge the physical addresses of safe houses and business premises… It is used as an excuse not to continue with the various investigations or to hamper these investigations," he said.
"As part of my investigations, it became evident that the classification of documents was used precisely to cover up fraud and corruption... and protect individuals in such incidences.
"I think many of the classified documents were incorrectly classified where the information contained inside did not warrant the type of classification."
His testimony is continuing.
