Powerful article. What strikes me as a layman (non-lawyer, non-law enforcement), is how prevalent these methods of forensic science have become, without any solid scientific basis backing them up - such as peer reviewed studies with quantifiable evidence. You'd think that in order for the state to take the life of a human being, you'd need to prove it using means that are more thoroughly vetted than "[one doctor] who in 1971 suggested the cause might be violent shaking" (emphasis mine).

You sometimes get the stereotypical esoteric forensics experts, who tour the country saying they have some special ability to identify bites or toeprints or whatever. I pretty much agree with you there; their methods are unproven, there's very little reason to think they can actually do what they claim, judges simply shouldn't let them testify.

This case is harder. Medical questions about what happened to a victim are often highly relevant, and doctors are legitimate, credentialed experts qualified to speak on that topic. If they believe based on their training and experience that suchandsuch symptoms mean blunt force trauma, how could a random judge evaluate whether they have enough scientific backing to say that?
