Woodcock commented about SC's clean feet and overall state of cleanliness. He was a firearms officer. Not ballistics, biologist or pathologist. There was no reason SC would not appear as she did having carried out the murders and shot herself with the firearm found across her body which was small calibre and fired low velocity ammunition (sub-sonic).
The pathologist found nothing to contradict the murder/suicide theory and he was the person trained to spot such inconsistencies eg SC's clean feet and overall state of cleanliness.
As you well know, had the Patholigist been called to the murder scene this may well have been different, all he had at this time was the Body.
Doesn't matter what you say about Woodcock, you said none of the raid team though it was nothing but Murder suicide, Woodcock didn't think it was. He discussed several things he wasn't happy with, the two shots under the chin, the bullet cases and the ejection from the rifle, and other things.
