I read with a sense of relief, in the Mail on Sunday, that Michael Howard, is to lead the call for an enquiry into the death of Dr David Kelly http://tinyurl.com/392f64j 
I cannot understand, given the obvious, huge, question marks hanging over the cause of his death, why this has taken so long.
The ulnar artery is tiny and not easy to get at. Due to the presence of coagulating enzymes in the blood, if Dr Kelly had managed to rupture the ulnar artery, using the blunt vegetable knife, it would have naturally stopped bleeding at any point from three minutes onward.

Could the grass have absorbed enough of the blood, which would have been thickening by the second, straight into the soil without trace? If he had lost enough blood via the ulnar artery to kill him within the three (can be up to 7-8)  minutes then surely it would have been too much to have been absorbed and there would have been puddles of coagulated blood lying on top of the grass.

Obviously, I'm no expert, however, it doesn't take a huge amount of knowledge to smell a rat.

Well done to Michael Howard. Bring on a full and official enquirey. His family deserve that at the very least.
