If your scenario above is accurate then I would doubt the LCN results too, but as you are wildly speculating then we don't have to be as negative. As you pointed out the LCN results were known before Hanratty was exhumed, therefore the profiles of VS and MG (his AB secretory semen was identified in 1961) could be extracted from the results and the remaining alleles would therefore be the rapists. If this matched point for point Hanratty's DNA profile then your "cherry picked" and stochastic effects can be totally ignored.
However, we don't have the exact results but Bindman does and presumably Woffinden too.
MG's DNA was only attributed to him. Somebody recently said that his son may have provided a DNA sample for referential purposes. But that is not good enough in this case.
A full referential profile of MG is the only thing that would be satisfactory. I have no record of MG being exhumed so that still leaves MG's profile as being completely uncertain.

As you are so insistent on this point, presumably you are in full agreement that Hanratty's exhumation was necessary.
This still leaves the unknown factor.
How many of VS, MG and JH's alleles where the same at any loci?
Noone knows.

With LCN it is certain that unreliable allele peak heights make mixed profiles impossible to interpret reliably. Certainly not reliable enough to put before a court of law.
The comparitive database is very small and is certainly not comprehensive as Sir Alec Jeffreys is at pains to point out. Jeffreys opposes the NDNAD in its current government controlled guise. He supports a totally inclusive NDNAD overseen by a completely independent body.
I don't see that happening any day soon though!
