Reliable eye-witnesses can report relevant observations of past events-about who, what, where, when, how, and why-verifiable clues needed for understanding or solving a mystery about what really happened, including “whodunit”. However, for complete accuracy, there is nothing that adequately substitutes for a reliable eye-witness. Yet what is the underlying “bread and butter” of forensic science?Ĭarefully examining physical effects in the present (perhaps with a magnifying glass, like Sherlock Holmes, or with more advanced technology), produced by physical causes of the past, is extremely helpful for learning about past events. To know the certainty of historic facts, especially non-repeating events that are no longer observable to us (or to anyone else), must we have an eye-witness report? In a word, yes - this is basic forensic science.Īfter the fact, historic causes routinely leave behind physical effects, often with observable characteristics (such as fingerprints, tire or shoe tread impressions, blood spatter patterns, nuclear DNA, mitochondrial DNA, etc.) that can provide reliable inferences about what occurred, earlier, at a specific location. How was the German battleship Tirpitz sunk, during World War II?
