Forensic labs explore blind testing to prevent errors

Science AAAS Kelly Servick 3o July 2015

Last week, at the first International Symposium on Forensic Science Error Management in Arlington, Virginia, nearly 500 forensic scientists, crime lab managers, and other practitioners confronted the factors that have led to unreliable results in the field. A key problem, many said, is that people who evaluate evidence from crime scenes have access to information about a case that could bias their analysis. That subconscious bias could arise from irrelevant contextual information, such as the nature of the crime or police investigators’ beliefs about a suspect’s guilt, or from the physical evidence itself. As forensics struggles to recover from revelations of serious flaws in its methodology and scientific underpinnings, more labs are considering ways to shield their examiners from potential bias.

CSI Sydney: Crime scene investigators use lasers and 3D goggles to map inside of Lindt Cafe

ABC News 31 July 2015

Advances in laser and 3D technologies are allowing police to reconstruct entire crime scenes and pieces of evidence.
The technology is being used in the inquest into last year’s Lindt Cafe siege in Sydney, and it is hoped that it will help in counter-terrorism activities.
Forensic crime scene officer Domenic Raneri says the days of measuring crime scenes with a piece of string are over.
“The laser sweeps out 270 degrees which means it’s capturing everything except for a very small area immediately below the scanner,” he said.
He said each scan takes about five minutes to complete.
“We can move through the crime scene taking these scans and overlaying them with photography to create a colour photo-realistic rendering of the environment,” he said.
