We need to rethink the relationship between forensic science and the law

The Conversation Sue Black, Niamh Mic Daeid 20 February 2015

Despite what we see on television, forensic science is not always easy to understand or simple to convey to a jury, many of whom may not have studied science since they were in school. When a case fails in the courtroom, maybe because the scientist was inexperienced, or there were flaws in the science presented, it creates the potential for a miscarriage of justice – something to be avoided at all costs.

Gold Coast murder victim not a ‘nice person’, but did not deserve death: Court

Brisbane Times AAP February 19, 2015

A Gold Coast man allegedly beaten to death in a savage attack “wasn’t a very nice person” but that didn’t justify his death, a court has heard.
