some alternatives for when and how the DNA came to be on the clasp
This looks like a good start. I think that deliberate contamination is the same thing as evidence tampering and would use the latter term. We might also note that the police only have control over a piece of item at some point after a crime is committed, and DNA could be transferred innocently, either before or after the crime, but before the evidence is taken into custody. I think that 4 is less likely than 2.Chris, if we accept Raffaele never touched the clasp, there might be four possibilities
1. Accidental contamination, R dna on clasp.
2. Deliberate contamination, R dna on clasp.
3. R dna not on clasp, accidental machine contamination.
4. R dna not on clasp, deliberate machine contamination.
Is this right, and are there other possibilities?
Can any of these be ruled out?
