Intelligent police holsters and glasses, facial recognition software and simulation tools able to mimic individuals all tout to be able to aid authorities in fighting crime and managing crowds. When a police officer draws an item, such as a taser or gun, from one of the holsters attached to his belt, the sensor in the holster instantly triggers specially designed glasses to take a photo of his surroundings. The images transmitted can help the command centre to determine if more manpower is needed on the ground, and also help to shape a response strategy. They also provide public safety and security agencies with the critical intelligence they need to anticipate and predict threats.
