I did the "Introduction to Forensic Science" course. Over six weeks, we gradually heard more about the evidence in a murder case, from the blodstains and fingerprints to the trajectory of the bullets. It was based on a real case. That was excellent too, lots of factual stuff about the different types of forensic evidence and how it is detected and analysed, interspersed with interviews with the people involved and accounts of how the results of tests threw light on what had happened (and on the discrepancies in witness statements.
It does show up the mistakes in detective stories!
Nxt week I am signed up to start the "Forensic Psychology" course, on what people say and what they mean.
I am looking out for "Identifying the dead" too.
