THE POLICING

POLICE AIDS

· The smart guns that can only

be used by police officers

Colt’s Manufacturing Company in the USA is currently developing an automatic pistol that will only shoot if it is in the hands of a police officer. The gun will fire after it receives signal from a radar that can be housed in a ring, watch or button worn by a police officer.

· The radar that can sense

breathing through a wall

A research team at Georgia Tech Research Institute in Atlanta. USA, has built a prototype radar torch which uses a signal processing chip to detect people through walls. To date, the torch can detect the subtle movement of a person breathing through a wall 20 cm thick.

FORENSICS

· Goggles which make evidence

glow for investigators

Researchers at Sandia National Labs in New Mexico. USA, have come up with a time saving and illuminating way for officers to pinpoint potential evidence at a crime scene; by making it glow. Exploiting the fact that most organic materials give off a natural fluorescence invisible to the human eye, the team have combined a flashing lamp and a modified pair of 3-D game goggles to make substances such as blood, semen body tissue, drugs and explosives flash to the wearer of the goggles.

· Robot investigators could

reconstruct the crime scene

The FBI forces that the growth of identity databases will lead to forensic robots filming and combing crime scenes for evidence and then being able to analyse it on sight. The information could be used to reconstruct the crime scene in virtual reality which human investigators or even a jury could refer to at any time.

JAIL SYSTEMS

· UK id tags allow prisoners

to be released early

In the UK, from 1999, some prisoners will be electronically tagged. Once fitted, a tag’s electronic signal is monitored, allowing police to ascertain the offender’s exact whereabouts so that many prisoners can be released early.

· Indestructible id tags

in development

Philips Research in the Netherlands is developing flexible plastic id tags that defy being squashed or folded. The two-way radar circuitry is etched with ultraviolet light into foil within the tag.

House-arrest offenders

monitored by satellite

US company Pro-Tech Monitoring testing a device called Smart (Satellite Monitoring and Remote Tracking system) which allows a central office to track the movements of an offender who is under house arrest.
