She turned them over to the sheriffs dept yesterday, on CD. They are analyzing them.
Mr G could put those tapes together here, without ever having met the man or spoken to him. Just getting hold of his movies would be all he needs, to get his voice. Analyzing them won’t tell you much, unless the guy was really sloppy about it. If you don’t have the original files (nobody uses tapes any more... all done in computers)it is hard to tell where the editing has been done.
