Forensic Science Regulator and Biometrics Strategy Bill

Debate between Julie Marson and Chris Green

2nd reading & 2nd reading: House of Commons
Friday 25th September 2020 Commons Chamber

[Chris Green]

Thank you, Madam Deputy Speaker. I will pick up the point that was made about public perception, because the regulator has a role in reassuring people that the system—all elements of the forensics science area—is up to standard. The public need that reassurance.

To some extent, that goes back to the “CSI” vision in that area. Before coming here, I worked in the mass spectrometry industry and on occasion worked in forensics laboratories. Having been there, I am confident that—not being a big fan of the show—there is a world of difference between the two. The laboratory environment is incredibly focused and serious. It has many of the standards and expectations that any other laboratory environment would expect to have, whether in industry or other sorts of research, because we cannot have scientists and others contaminating samples in the lab with DNA or other samples, for example.

We have to have a clean-room environment and incredibly well-controlled samples and other materials. We hear about the negativity of single-use plastics, but in the laboratory environment it is incredibly important that people use a vial once and not on a number of occasions, because that is how we get cross-contamination.

We have to have an understanding of the quality of the science and the resources it needs because of the sensitivity of instrumentation these days. I worked in the mass spec industry for approaching 20 years, and the technology was transformed from the beginning of that time to when I left. Having been here for five years, I would now feel, in a sense, technologically redundant. I have been completely left behind. It is not just the physical technology and the electronics; it is also the software. In terms of the laboratory experience, this touches on wider concerns about data handling and how we can control and protect the enormous quantities of data that laboratories generate. We must have confidence, from beginning to end, about how the samples are gained from the crime scene, how they are processed and transferred, and how they go through the laboratory system, after which reports are written and, ultimately, presented in court.

[Julie Marson (Hertford and Stortford) (Con)]

The whole question of confidence makes me think of rape victims, for example. The rate of conviction in this country and elsewhere for rape is shockingly low, and this question of confidence feeds into the very purpose of the Bill. The work of these laboratories is valuable, intense and professional. Does my hon. Friend agree that public knowledge about that would give victims the confidence to come forward and submit to intrusive examinations, because they know what will happen with their evidence? This is all about enforcing and reinforcing the justice system.

[Chris Green]

I agree entirely; my hon. Friend makes an important point. This legislation, and our having this debate, is incredibly important in giving victims the confidence to come forward and know that they will be looked after and supported in the right way. There would be an ongoing duty and responsibility for the Forensic Science Regulator to work to raise standards in the system, so that people can recognise that.

I have not touched much on the digital side of a forensic science laboratory’s work. I am more familiar with mass spec, high-performance liquid chromatography and the other analytical techniques that can be used. I was a member of the Science and Technology Committee from 2015 to 2017, and we went on a visit to the Laboratory of the Government Chemist in Teddington. I had worked there a little bit beforehand, but it was fascinating to see the digital side of its work. I want to give a sense of the challenge ahead and the resources required.

The police and forensic scientists have to monitor, judge, analyse and access smartphones, smart watches, iPads, computers, desktops and many other devices. All those devices have different levels of software, different editions, newer versions and different operating systems. We need to have a compliant system within the digital sphere to ensure that that analysis can be done in a way that cannot then be challenged or undermined in the court system, and it can be shown that these standards have been adhered to and in no way have the digital services interfered with or corrupted the data being drawn from these devices.
