As usual Lookout doesn't quite post the truth.
This is what he ACTUALLY says.
"I think the case would benefit from a new forensic examination of the remaining exhibits and photographs - particularly in relation to the analysis of the patterns of blood-splattering, which could provide additional and useful evidence.
What I find most frustrating is that, had modern DNA techniques and itemised billing for telephone calls been available in 1985, many of the doubts about this troubling case would have been laid to rest a long time "
The photos are not that good. They did not take closeups of all the spatter so as to allow reconstruction of events based on spatter. They can at best make isolated observations.
If itemized billing had been in use in 1985 it would have simply made it necessary for Jeremy to call his answering machine from WHF and it would show a call from WHF to his place or he could have turned it off, called his place, set the ringer on low so no one would hear it ring and let it ring until he got home and answered. Then it would show up as a call from WHF to Goldhanger.
The only way itemized billing would have helped is if Jeremy didn't know about such and thus didn't fake a call to himself in which case his lie would be easily busted.
Itemized billing would have forced him to use the car instead of leaving him the option of the bike because he would have needed to get home faster and instead of dissuading supporters the fact a call was made would further embolden them. The Campaign Team would be insisting it was Nevill who called and would deny to the hilt that Jeremy faked the call.
