| Summary/Abstract |
Few years ago, the National Geographic channel aired a series of documentaries on the best cities in the world. The series was called ‘Mega Cities’. In each episode, the programme documented one major city and showcased why it was considered one of the best. The show seemed to have evaluated the cities on various parameters like safety and security, trade, efficient transportation and so on. One of the most striking episodes in the series was on London – the city which invested a lot of its resources and manpower in setting up the most intricate and efficient surveillance systems using CCTV cameras.
