Currently, the availability of optical topography instruments – 3D technologies, have become more accessible for forensic laboratories. Due to the precision and accuracy of these instruments, the scientific community of forensic Firearms/Toolmarks (F/T) identification has begun to investigate their utility in forensic F/T casework.
To provide guidance and recommendations to the F/T community in instrument assessment and Virtual Comparison Microscopy (VCM).
Creating standards for the F/T community to establish acceptable measuring practices, methodology/Standard Operating Procedures (SOPs), and quality assurance protocols that can be utilized to access a laboratory’s compliance during accreditation.
The TWG3D2T membership is comprised of state, local, private, federal, and international forensic firearms and toolmark examiners along with academia, research metrologists, and legal professionals.
