Yea, but there is definitely a gradient or propensity of evidence that is often lost. For instance, touch transfer DNA can deposit your DNA on a crime scene if you interacted with the EMTs earlier in the day (Anderson case, 2012) [1] which means very little, but if a suspect's fingerprint is in the victim's blood, it's very likely the suspect was present during an attack. In the later case, I think DNA evidence, the victim's in the case, would be evidence of guilt, but needs to be part of a larger, coherent case.
