The Crucial Role of Forensic Science in Upholding Social Justice
With being observed on February 20th, this blog post focusses on the crucial role that forensic science and technology plays in helping to ensure social justice is upheld and advanced across the globe.
The United Nations World Day of Social Justice represents a global commitment to promoting social justice, equality, and the fair treatment of all individuals, regardless of race, gender, religion, or socioeconomic status. Established in 2007, this commemorative day serves as a reminder of the international community’s shared responsibility to address social injustices and create a more inclusive and equitable world for present and future generations.
Background
How can forensic science uphold social justice?
For as long as the law has been enforced, it has been susceptible to bias, corruption, and the malignant influence of wider social inequalities, often resulting in terrible miscarriages of justice. The countless injustices of the colonial period, witch trials of the 16th and 17th centuries, or the case of , represent but a small selection of examples that demonstrate the vulnerability of justice systems to influence from racism, social prejudices, discrimination and personal grudges. Thankfully, in many modern cases, forensic evidence provides crucial impartiality and challenges the power of prejudice, preventing and overturning verdicts that may otherwise have been based on discriminatory beliefs.
In a world where justice is paramount for social harmony, forensic science stands as a cornerstone in the pursuit of truth and fairness, serving as more than just a tool for solving crimes. The objective nature of the discipline can ensure that the innocent are exonerated, the guilty are held accountable, and that truth can prevail amidst ambiguity, regardless of the effect of social injustices or biases. More than this, forensic science has the potential to address systemic biases themselves and contribute to a more just world for all.
Read on as we consider examples of how forensic science has upheld social justice, and how modern technologies are making it easier than ever to produce the quality forensic evidence necessary to achieve this.
DNA Evidence
Since its inception in 1992, , a non-profit organization dedicated to exonerating wrongfully convicted individuals, has utilized DNA analysis to overturn wrongful convictions. We can consider , who was convicted in 1984 of raping Jennifer Thompson-Cannino in North Carolina.
Advances in forensic technology have vastly increased the ability of forensic examiners to screen for, capture and analyse body fluids and other physical evidence such as hair or fingernails at the crime-scene, allowing DNA to be collected and used as evidence in court. Multispectral alternative light sources, as found within our Crime-lite Range, empower CSIs to search for evidence using a range of wavelengths, with single devices such as the revolutionary Crime-lite AUTO now capable of providing illumination across the electromagnetic spectrum, imaging evidence through appropriate filters and capturing quality, court-ready photographic evidence. You can learn more about this process of fluorescence imaging with bandpass filters here.
A recent collaborative study between foster+freeman and L’Institut de Recherche Criminelle de la Gendarmerie Nationale (IRCGN) examined the modern methods used to identify body fluids on forensic evidence

Trace Evidence
The forensic analysis of trace evidence often plays a significant role in criminal investigations, providing the crucial link needed to make an arrest or secure a conviction. Trace evidence refers to small pieces of physical evidence, such as fibres, hair, glass fragments, and soil particles, that can be transferred between people, objects, and locations during a crime.
The forensic analysis of trace evidence plays a crucial role in determining the cause and origin of fires in arson investigations. By examining burn patterns, residue, accelerants, and other evidence collected from fire scenes, forensic scientists can reconstruct the events leading up to the fire and identify potential arsonists.
Advancements in forensic technology make it easier for examiners to identify and examine trace evidence relating to a crime. During investigations, the use of alternate light sources to detect trace evidence is now commonplace, with advances in multispectral imaging and filters allowing examiners to detect evidence that would have otherwise been invisible to the naked eye. Enhancements in portable LASER technology led to the development of our Crime-lite LASER, further increasing the ability of examiners at the crime-scene to identify even the faintest traces of evidence.
Recovered items relating to an investigation can also be examined in a laboratory to identify trace evidence present. Devices such as our Crime-lite ML PRO and DISCOVER system are ideal for conducting multispectral bulk searches, ensuring that maximum trace evidence can be recovered efficiently.
Once trace evidence has been identified it can be analysed, with various methods being employed depending on the type of evidence in question. The foster+freeman ffTA is a powerful and flexible multi-functional system that provides the crime laboratory with a range of analytical facilities on a single microscope. The capabilities of the ffTA include glass refractive index measurement, multi-wavelength Raman Spectroscopy, light polarisation, fluorescence imaging and UV-Vis-IR micro spectroscopy.

Fingerprint Evidence
At the turn of the millennium attitudes towards digital photography changed as foster+freeman, in close collaboration with Wiltshire Constabulary, launched the DCS 121, a digital photography system offering tamperproof image validation software. As technology has progressed, so too has the DCS, with today’s DCS 5 representing a no-compromise imaging system for the illumination, visualisation, photography, and enhancement of almost any type of fingerprint on any surface or background, ensuring that maximum detail is revealed.
In order to be successfully imaged and analysed, many fingermarks require preliminary chemical treatment. Our industry-standard MVC Range of fuming cabinets are used globally to this end, with our unique RECOVER LFT featuring a cutting-edge chemical vapor fuming process to develop fingerprints on a range of difficult surfaces. RECOVER LFT is unique in its capability in developing fingermarks which have been exposed to extreme heat (discharged bullet casings, for example) and items that have been washed ‘clean’ in an attempt to prevent identification.

Questioned Documents
Document fraud has been referred to as an ‘engine of organised crime’, and plays a major role the ability of criminal gangs to corrupt and undermine social justice internationally. You can learn more in our recent blog post: Document Fraud: An Engine of Organised Crime.
By exposing fraudulent identity documents, forensic analysis helps uphold immigration laws, protect national security, and maintain the integrity of identity verification processes. Our VSC Range of document examination workstations represent best-in-class performance, providing examiners with a complete solution to the examination of questioned documents.
Conclusion
These examples illustrate the multifaceted role of forensic science in upholding social justice, from rectifying wrongful convictions to ensuring the guilty are brought to justice. We can also see how forensic science is able to provide confidence in the impartiality of our legal justice systems, providing a robust barrier to the influences of corruption, bias, prejudice and discrimination.
Forensic science acts as a beacon of hope in the pursuit of social justice, offering clarity amidst complexity and providing accountability in the face of wrongdoing.
By exonerating the innocent, uncovering truth, holding the guilty accountable, addressing biases, and embracing technological advancements, forensic science reinforces the foundations of a fair and equitable society.
As we recognise the importance of social justice on 20th February, we can also be proud to celebrate the role crucial role forensic science plays in ensuring it is upheld. In the years ahead, we are committed to continuing to enhance the quality and integrity of forensic evidence through innovation, and advocate for its ethical and responsible use in the service of justice.
