It is commonsense that criminals do not want to be identified at any time, before, during or after their misdeeds. To stop the bombers:
1) Instal CCTV cameras on top of high poles at strategic entry points to crowded markets, mandhirs, masjids and so on. 2) At traffic junctions, nodal points, install a high "observation tower" - army style - to keep an eye on cars, scooters and their drivers. 3) A compulsory register for sale of Ammonium Nitrate, Gelignite and other explosives. 4) Enforce the existing requirements for sale of mobile phone SIM cards. If you are lax the SIM cards would become SIMI cards used in killing innocent people. 5) In China every street has an Intelligence official to keep an eye on new-comers and vehicles new to the area. Boost the personnel of the intelligence services. 6) Develop a "security culture", as the experts like Ved Bharadwaj are asking.
