So you want to say, if intelligence of a country protects VIP then it can not protect country ? FYI intelligence do not protect VIPs. It provides its feedback and input to security forces like NSG, CISF, STF commandos when there is threat to their life. When you become a minister you will also like to protect your childs. Problem here is local network intelligence which is not working. Intelligence, police, govt does not keep any record who is living in a local area, from where he is coming and going. They need to verify each person even he is a normal civilian. We do not have left any other way. We need to act same every time what we do after blast i.e. make searches, get sniffer dogs etc. Then only perhaps we could avoid such incidences. Otherwise bhagwaan hi maalik hain..
