The twin blast at residential building in Abass Town killed more than 46 people and also wounded around 140 people. Many children were also killed in the tragic incident. According to reports, the Police and law enforcement agencies reached the incident after one hour and this delay was because hundreds of police was present at the engagement ceremony of PPP leader Sharmila Farooqi at Mohatta Palace. After few hours of attack many people started criticizing Sharmila Farooqi and Karachi police on social networking websites. It is time that CCTV cameras are installed in Karachi in massive numbers. I have read many times that around 3000-4000 CCTV cameras are already installed in different zones of Karachi. From Toll plaza of Karachi to all the main roads, roads, streets hence all road should be covered by the CCTV system which should be linked to command and control system. So whenever any incident happens (mobile snatching, dacoit, murder, and bomb blast) police can see from where the accused has come and where they fled. It is hoped that next government will make sure to do this; it will require lot of money but will ensure law and order in the metropolitan city.MUBASHIR MAHMOOD, Karachi, March 4.
