ANSWER
I must explain the normal way of informationevaluation to you.   We had various sources that were codifiedafter, according to the veracity of previous reports we had received.  Before a person was selected for elimination we investigatedhis file and there must have been very bad actions and thingsin the file before such a decision was taken.   There were alsovarious informants in the community who were given orders to investigatea specific target, to investigate him and to inform us about whathe was doing and then we received weekly reports.   If the personwas very active, we even received more than one report per informantper week.   This information was then worked into one documentfor easy reference purposes and when such a person was identified,or when it was decided to take action against him I can assureyou that it came from many various informants.
