Not sure what you mean Hartley. All I am saying is that there was no positive forensic evidence or the cops would have arrested Jeremy sooner.
What I meant is that it would make more sense to reference between circumstantial and direct evidence, rather than include the term forensic.
It's also worth noting that circumstantial does not mean 'weak', it just means that of itself it is not sufficient to prove guilt.
By that definition, if finger prints were found to be present, they would be forensic evidence, but they would also be circumstantial as you would be asking a jury to consider whether the prints could have been left at a particular time.
I suppose that by the same token, the blood tests in the silencer would be taken as being both forensic and circumstantial.
That's as I understand it anyway, perhaps Petey or NGB would have a more informed definition.
