Part autobiography, part thought piece, part references, the book takes an insightful look at the experience and cases of renowned paediatrician and forensic expert witness Dr. Charles Ferguson. The book presents the interaction of science and law as it applies, specifically, the Canadian courts, but the justice process as a whole. Dr. Ferguson’s experience—from a scientist and medical professional’s perspective—in dealing with lawyers, judges, and the process of testifying in numerous court—offers a unique glimpse into how the two worlds of science and law don’t always mesh. In some cases the evidence is compelling and definitive. In others, far from it. Ultimately, the book presents the important role of the forensic expert and expert witness as a vital and deciding factor as the courtroom proceedings play out.
