Three Royal Marines Court-Martialled for murder of Afghan insurgent

In this case, we were instructed by the prosecution to transcribe the content of utterances and attribute them to Marines in videos made on a helmet-mounted camera.  The camera was worn by ‘Marine B’ and filmed a team on a battle damage assessment after an Apache helicopter engaged an armed Afghan man. Three marines were charged and one, ‘Marine A’ – an experienced sergeant, was found guilty.  The other two marines were acquitted.  An article from the Guardian explains the role of the transcript:

George Zimmerman & Trayvon Martin

Murder case in the state of Florida |

In this case, which received international attention, we were engaged by the defence to provide an expert assessment of speech evidence submitted.  This testimony was entered into a Frye hearing on the admissibility of speech evidence where one sample featured distress screams.  Using our experience and knowledge, and relying on research carried out in partnership with the University of York, we provided a number of conclusions which were put forward by Prof French via video-link.  The Judge ruled in favour of the defence, stating:

Defense witness Dr. French, regarded as an international expert in the field of forensic speech analysis, has worked in the field since the late 1980′s. The Court found the testimony of Dr. French to be the most compelling of the witnesses presented.

R -v- Gary Moore & others

ENF & authentication analysis in drug-trafficking trial | 

In the case of Gary Moore & others, our authentication expert used Electrical Frequency Analysis (ENF) to determine whether a series of surveillance recordings had been edited.  Alongside a range of other authentication techniques, the ENF system was able to determine that there was a very high probability that the police recordings had not been edited.
