I think they also exceeded their brief. They've gone off the logs timing for female body found downstairs, for SC. That might have been considered a bit cheeky. They've also been a bit free with the time Bamber was with police. However it's the oxygenated blood that is the main thing surely? What on earth is blood doing separately pooling in the way it has across her neck anyway.
I would like to have seen these blood expert's interviewed for the last documentary , i believe it would open a lot of people's eyes to this case also if GDS , ES , BW and Mr Rivilin and anyone else who as represented JB could be interviewed for a similar documentary , i believe the general public would be outraged by the obstacle's put in front of these people over the past 27 year's !!
