I think you did as professional a job as anyone could have with these recordings, Dave. It is obvious to me, especially after listening to the looped noises, that these are artifacts of the 911 recording system, probably the tape recording device. It goes beyond imagination to find anything else on this tape.

Not the smoking gun it was supposed to be, and while not the elimination of the RDI theory, it IS an indictment of the Boulder Police Department's misinvestigation. Absolutely mind boggling that anyone would try to make something of this. Was this pathetic grasping at straws or criminal misrepresentation?
