Its weired. So many live bombs are being discovered (only) from Surat. But none of them is exploding. Why ? Let us say, police found 5 live bombs in Surat and there are still 5 more to be discovered, then why not even 1 one of them is exploding ? Do you think, terrorists are fools? They will just keep the bomb anywhere and wait for the police to find them. We should not forget that the terrorists have one of the finest brain (though they use it for desructive purposes).
