I'm asking the question because there's a story in today's Globe and Mail by Graeme Smith that documents the case of a suspect, a detainee--excuse me if I don't have exactly the same language you do--who was detained over the death of Glyn Berry. He documents very forcefully in his article today that a Mr. Pir Mohammed was arrested as a main suspect. They said the police became more suspicious after they raided his home, finding weapons, documents, and a Kalashnikov, but before a proper investigation could take place, he was released after less than two days in custody because, according to this article, Mr. Mohammed had friends in high places, powerful men who gave him freedom before the police were satisfied that they had had an opportunity to properly investigate him. Apparently the key to his release was Mullah Naqib. It was said that Mr. Muhammed was lucky enough to be born as a member into this old warlord's tribe.
It does raise some very serious concerns, particularly when we're talking about the life of a Canadian diplomat and the investigation or lack of investigation thereafter.
