According to a recent US police report, when news of a fight broke out during a San Francisco 49ers' game last year, the Santa Clara Police Department was able to pinpoint the victim's precise location in the stadium, as well as take the suspects into custody, all within three minutes. The swift response was owed to a "smart mapping" platform the police had adopted, known as Geographic Information System (GIS) technology. It allows information aggregated from various data sources, such as security cameras and social media feeds, to be plotted on a map, helping officers collate and make sense of what is happening. Besides being an important tool for law enforcement agencies to react and respond to cases of public safety, GIS technology can be used in areas of supply chain security and cybersecurity. The technology is already being tested in Singapore".

With reference to the above report:

(a) Distinguish the characteristics and effectiveness of new-generation technologies in combating and preventing crime

(b) Contrast the feasibility of such technologies in the public sector with the private sector in Singapore.
