I don't think so. Not anything that will hurt them badly. Media and politicians will make a mockery of the dead and injured by dragging it for years without any result. Police and other security machinery are sleeping when the incident happened? Security people of each state share information with each other and are well networked, they have moles and informants in every corner who give them updates. These guys can be excused if it happens once or twice, the first few times as incidents like these would be new to them. But even after so many incidents these guys are doing nothing to stop such incidents. It's really shameful. They are giving moral boost to terrorists.
