Notable Cases

R v VENABLES and THOMPSON – Murder of James Bulger

John analysed low-resolution video images (CCTV) of James Bulger’s abduction from the New Strand Shopping Centre by two, at the time, unidentified individuals. John also had responsibility for equipping the Courtroom with all of the CCTV and Audio evidence used during the trial.


R v Nico BENTO – Miscarriage of Justice

Bento had been charged with the murder of his girlfriend. The Prosecution case relied entirely on CCTV evidence. John, then a Consultant Forensic Scientist with the Government owned Forensic Science Service (FSS), was instructed by the Crown and raised concerns about the CCTV and if in fact, this was ever a murder. John had recommended a particular forensic process involving Reverse Projection but the Crown failed to act on his advice and instead instructed an American expert. The defendant was convicted on the evidence provided by the American expert and was sentenced to life imprisonment. John feared that there had been a terrible miscarriage of justice and tried to persuade the Forensic Science Service to alert the court. They refused and prevented him from pursuing the matter. John resigned and despite having a ‘gagging order’ placed on him by the FSS, he went on to help launch an appeal against the conviction. The Lord Chief Justice ordered the prosecution to undertake the forensic process which John had recommended during the early part of the investigation. That process, undertaken jointly by the Crown and the Defence, entirely undermined the CCTV evidence and the evidence given by the American expert. The conviction was quashed and a new trial ordered. The Crown subsequently offered no evidence. Nico Bento was subsequently awarded substantial damages. This case resulted in numerous TV documentaries including a full feature on BBC Newsnight.  


Assassination of Rafic HARIRI, the former Prime Minister of Lebanon

John was consulted by the United Nations Security Council in connection with the CCTV evidence which captured events leading up to and including the assassination.


Cases of terrorism in Northern Ireland

John has provided evidence in numerous terrorism related investigations in Northern Ireland, including the Birmingham bombings.

Additionally, John has been involved in the examination of “trophy recordings” allegedly made by Boko Haram soldiers concerning various atrocities including the mass execution of villagers in the region.  


“In light of all of your scene examination and other CCTV evidence - we made further representations to the prosecution counsel. He reviewed this and offered no evidence! Such a great result for the client. Thank you for your hard work.” 

Solicitor, Lewis Nedas Law
