Mumbai says, "Bomb blasts are just a minor part of the problem". That gives you some idea about the anger thats building up with in the city. The city reportedly contributes to 1/3rd of the total national tax revenue and yet has to grapple with the most basics of infrastructural problems like the rest of the country. The problems are so acute that people think that bomb blasts are just a minor part of it! Bomb blasts happen may be once every two years (I am ashamed to give a periodicity to the acts of terror, but thats the periodicity history indicates), but the infrastructural problems are to be fought with every minute. And yet red tape, bureaucracy, corrupt politicians, inefficient systems get nothing done. Naturally, its residents are angry but dont know where to direct it.
Its important that all this building anger is let out before pseudo outlets (like 'Maoists', balkanization of communities based on religion etc) become more popular.
