Quite correct!Without active involvement, support-whether direct or tacit of local people it is impossible for the terrorists to carry out such diabolic operation which involves several intricate aspects such as identification of the places,extent of busyness of the place,extent of traffic,routes to the areas for the operators to get into and also to escape etc..The black sheep who helped & abetted the crime should be culled out & brought to book at the earliest.People in the are concerned should also circumspect the movements/actions of such people since it is impossible for any investigating agency to identify them timely such blood thirsty wolfs in disguise of goats.The religious leaders to which such traitors belong to should also identify & preach the misguided how serious their crime is & make all out efforts to put them back on the right track so as to enable them fall in the main stream of society.There is a proverb in one of the vernacular languages which says that"a thief in his own house cannot be caught even by the God" for a simple reason that none suspects their own man to be a culprit in the crime committed towards his own people. The local accomplices hardly realise that their actions resorted to either by misguidance or for money will engulf one day or other their own people & they cannot go uncaught for all times.A sin cannot escape for ever & when it ripens its manifestation will be terrible making their lives unimaginably unbearable.Law has long hands.
