"His interview was in 1991 and was recorded and this is the transcript:
http://jeremybamberforum.co.uk/index.php/topic,590.msg12022.html#msg12022
He stated he had no idea a moderator was collected in this case until many months later. Thus when he overheard Cook talking with the lab about pain be assumed the paint was on a rifle he didn't realize it was on a moderator."
He said no such thing, you have made that up...
Unlike you I don't make things up. All on need do is read the statement to see that it contains nothing about fingerprinted a moderator in connection with the case let alone doing so on Aug 9. If you actually read the link it would have same you embarrassment from having me prove you ignored the following quotes but then again this is not the first time I highlighted the following quotes and that you ignored them. You ignore what is actually written and just characterize things however you desire instead of accurately describing what witnesses state:
COLP established he had no involvement in the collection of the moderator and it was sent to the lab on his day off so he was not involved in the paperwork of that initial submission. He said he was thus unaware the moderator had been collected and unaware of its significance:


Because he was completely uninvolved in anything to do with the moderator and never even saw it until COLP showed it to him he had no idea paint and blood was found in/on it:

Thus when he eavesdropped on a conversation Cook was having with Elliot concerning the paint he assumed they found paint on the barrel of a gun found downstairs which had not been used to shoot anyone (he assumed they meant a rifle other than the murder weapon was used to beat Nevill and got paint on it) :

Davidson is unaware of any moderator other than the one turned over by the family which he didn't even know existed until much later in the case so thought Cook and Elliot were talking about paint on a rifle barrel and which he never saw at all until COLP showed it to him:

Thus not only did he not claim he fingerprinted a moderator on Aug 9, he never claimed he fingerprinted a moderator period. He said he never even saw a moderator until COLP showed it to him. He said he wasn't even aware of moderator had been collected until months after it had been examined and when he did learn about it finally he only heard of that single moderator not any others.
When one actually endeavors to comprehend his COLP statement this is what one comes away with. But you never set out to accurately recount thing you instead set out to pretend people said anything you desire.
"This means it is impossible for him to have fingerprinted any moderator in connection with this case ever let alone do so on August 9. He said he never saw the moderator to that day."
Well, he lied then, its as simple as that because he fingerprinted one silencer on the 9th August 1985, and he fingerprinted a second silencer with DS Eastwood on the 14th September 1985, so it just goes to show what a deviant he was...
So first you claim he admitted he fingerprinted it. Next you say I made up the things attributed to him. Now you say he lied but offer no evidence to prove it.
"How could he have fingerprinted a moderator he didn't know about or fingerprint one he never saw?"
So, the police documentation confirming he did carry out such fingerprinting duties on these 2 silencers has been fabricated by the police themselves, have they? For what purpose would they do that if it wasn't true?
You have not provided any documentation demonstrating he fingerprinted any moderators period let alone fingerprinted them on the dates you claim. COLP went through his pocketbook to discuss his activities and fingerprinting a moderator was not among them. In fact his only involvement in prints was filling out paperwork to transmit print cards taken by others to the lab. He wasn't even familiar with the results paperwork that comes back from the lab.

He was a paperwork guy he didn't take prints or collect evidence he filled out paperwork and sent items to the lab. Even on the day of the murders his role at WHF the day of the murders was to fill out paperwork to reflect what others had collected. He also filled out the paperwork at the Morgue and transported the fingerprint cards and other exhibits taken at the autopsies back to the station to then submit them for processing.
He didn't fingerprint anything himself. Nor did he examine any fingerprints to try to assess who they belonged to.
