Each time a bomb blast occurs our intelligence is baffled as if they need to call in Sherlock Holmes to investigate.  Despite a series of bomb blasts and loss of innocent lives, I am sorry to say, we are none the wiser.  You have a lesson or two to learn from the US where the so-called terrorists have turned tail after the 9/11 attack on WTC.  What’s the loud message it sends out?  The honey-moon period is over and time to get cracking.  You have a lot more to be done in terms of a foolproof security system which leaves much to be desired.  Remember, to undo a knot you have to undo a string.
