Why is DNA fingerprinting more conclusive when proving a person’s innocence rather than their guilt?
Likurg_2 [28]
DNA fingerprinting is far more conclusive because it is solid proof. It has evidence that a certain person was at a certain place at a particular time frame. Although most criminals do get asked to use the polygraph test, testing guilt I guess, measures only their heart rate. Which in a normal view many regular people would be nervous. There has been countless reports where murders can pass a polygraph test, but then be convicted of a crime due to proof of evidence from fingerprints. Humans are emotional beings, some can crack easily while some won't (through interrogation). So that's why it's key investigations use science to back up their crimes rather that try to measure someone's guilt.
