Answer

In the USA, research shows that although members of the public believe forensic science remains a key part of criminal investigation, they perceive a high risk of error ‘about half of the time at each stage’ of the forensic process. This makes the public sceptical about the accuracy of some forensic science techniques (Kaplan, et al., 2020). Generally, errors in forensic science can be caused by practitioner, analytical or systemic failures and may contribute to wrongful convictions. These mistakes are therefore drivers of distrust.

To help mitigate this, oversight and regulatory measures have been established in many jurisdictions, such as the Forensic Science Regulator in England and Wales and the Organisation of Scientific Area Committees (OSAC) for Forensic Science in the USA. These bodies aim to ensure and improve the quality and reliability of forensic evidence provision, such as by establishing quality standards, ensuring accreditation of forensic science service providers (FSPs), competency of practitioners and investigating and sanctioning FSPs for failures and practices that do not meet required standards.
