Here's a recent book that I purchased and highly recommend:
Evidence Matters - Science, Proof and Truth in the Law (2014, Cambridge U. Press) by
Susan Haack, one of my favorite female philosophers.

Here's Amazon's book-blurb:
"Is truth in the law just plain truth - or something sui generis? Is a trial a search for truth? Do adversarial procedures and exclusionary rules of evidence enable, or impede, the accurate determination of factual issues? Can degrees of proof be identified with mathematical probabilities? What role can statistical evidence properly play? How can courts best handle the scientific testimony on which cases sometimes turn? How are they to distinguish reliable scientific testimony from unreliable hokum? The dozen interdisciplinary essays collected here explore a whole nexus of such questions about science, proof, and truth in the law."
Susan Haack writes:
"The mathematical calculus of probabilities is perfectly fine
in its place, but that place is a limited one. In particular, this mathematical calculus sheds little or no light on the crucial concept Russell calls "rational credibility" and I call "warrant". One consequence, as I shall argue here, is that we can't look to probability theory for an understanding of degrees and standards of proof in the law, but must look, instead, to an older and less formal branch of inquiry: epistemology."
