Súper-detectores: entrevistas policiales para identificación forense de sospechosos a partir de imágenes de CCTV


Oferta Tecnológica
Una universidad británica ha desarrollado métodos para examinar las capacidades cognitivas de agentes de policía que han llevado a cabo numerosas identificaciones de sospechosos a partir de imágenes de CCTV (súper-detectores). Estos métodos suponen una ventaja en las investigaciones criminales de profesiones legales, ya que aumentan la probabilidad de que los delincuentes que han cometido un crimen sean acusados. Esta técnica ofrece un gran potencial en investigaciones futuras, especialmente en la investigación de los métodos empleados por la policía de otros países para identificar sospechosos. La universidad busca colaboración con fuerzas policiales y socios potenciales especializados en reconocimiento, cognición y criminología.


Super-recognisers - Police interviewing for the forensic identification of suspects from CCTV, facial composites and descriptions
A UK university has developed methods to examine the cognitive abilities of police service officers who have made a large number of identifications of suspects from CCTV images (super-recognisers). The methods benefit legal professions in their criminal investigations as they enhance the likelihood that offenders who have committed crimes will be charged. Suppliers to police forces, those working in recognition, cognition, criminology, law, sought for joint ventures and research cooperation.
The August 2011 riots in many English cities cast a heavy pall across the country. It was extremely distressing for most members of the public who stayed in their homes to avoid nearly a week of crime-riddled evenings.

In London, a substantial proportion of all suspect arrests were a direct consequence of identifications from CCTV made by a small group of front-line police officers -- so-called super-recognisers. One identified 180 sometimes heavily disguised rioters. As the majority of suspects confess when confronted by such evidence, these officers were clearly somewhat special.

Some super-recognisers had already come to the attention of the Metropolitan Police Service due to a steady stream of previous CCTV identification successes. As a consequence, the psychologists detailed in this profile, had tested the facial-recognition and other cognitive abilities of these officers to determine whether they possessed exceptional skills.

There was a strong sense of outrage and demand for retribution. However, unless a suspect was apprehended at the scene, for the police, the thousands of hours of CCTV footage was in many cases the only evidence linking offenders to their lawlessness.

There are a number of elements to the methods described, however, they primarily involve human cognitive processes - memory and perception in a forensic setting. For instance, face recognition and so called ´super-recognisers´ who never forget a face, eyewitness identification by people in the normal range of face recognition ability and the techniques used by the police to gather reliable evidence - e.g., lineups or identity parades.

Additional work examines the development of computerised facial composite systems used by police operators to recreate the witness´s memory of an offender as well as techniques used by experts in court to demonstrate that the same person is depicted in two different evidential photographs. Finally, additional examinations have tested the reliability of human identification of offenders in security camera images.

The university seeks partnerships with those supplying to police forces, those working in recognition, cognition, criminology and law to test and further develop the system via collaborative research and joint ventures. The methods have the potential for substantial improvement but partnerships are critical to this being possible. Partners sought will benefit from the use of cutting edge methodology in their industry to help them cut costs and time in their day to day work whilst increasing whilst maintaining the highest standards.
Advantages and Innovations:
The biggest advantages of adopting such methods are the identification of personnel and their deployment in roles which reduce the time required for a conviction enormously.

Use of the methods also reduces the likelihood of a miscarriage of justice. The work on super-recognisers also provides information as to the maximum capabilities of the human memory and perceptual systems.
