8 Pocklingtons Walk,
What's the talk about?
A grisly murder scene, a renegade detective pours over the scene. They find an overlooked clue; a hair, a footprint, a shell casing. Detailed analysis matches it to the bad guy. The bad guy goes to jail - this is often how modern day forensics are thought of and how it is often portrayed in shows such as 'CSI' and 'Silent Witness'.
Forensic evidence is seen as conclusive when it comes to catching suspects and deciding if someone is guilty in a criminal trial. How could the traces left behind at a crime scene lie?
The science in areas such as DNA collection has progressed enormously in recent decades allowing for break-throughs in many old and cold cases.
However, we have also seen many high profile exonerations of those previously convicted of the most serious of crimes on seemingly 'conclusive' forensic evidence. This has lead to increasing scrutiny of the way it is analysed, interpreted and presented in the courtroom.
In this talk, prison lawyer Emma McClure explores this issue alongside the amusing, confusing and sometimes tragic consequences of failing to take a skeptical approach to scientific evidence.
