A South Coast architect caught with "degrading and disturbing" images of child pornography was sentenced to nine months' weekend detention in Wollongong Local Court yesterday.Magistrate Ian Guy said it was distressing that children were being emotionally and physically abused to feed a market for people whose sexual appetites had "descended to such a base level".Among the 381 images found on the work computer of Douglas John Riley were photographs depicting sexual intercourse between adults and young girls, and sexual activity between children.The children in the pictures ranged in age from one to 16 years.Mr Guy said: "Possession of this material will not be tolerated."It is not a victimless crime."He said while the 38-year-old was not the one sexually abusing the children, he was among those creating a market for others to do so.In an earlier court appearance, Riley had said he had a compulsion to view child pornography.However, Mr Guy said: "He is a well-educated man who understood the criminality of his actions."Australian Federal Police officers raided Riley's Vincentia home in June and the court heard yesterday that Riley was co-operative.Mr Guy said Riley's criminal behaviour was out of character, however, he could not suspend a jail sentence as it was important to send a message of deterrence.Riley was sentenced to a minimum of four months' weekend detention.
