Our political leaders (ruling one OR opposition)and our security agencies (inclding police & intelligence),they all have justification for not catching terrorists. Immediately after such incident, they give statements that it is ISI work and ISI is not in India. Otherwise they will name the involvement of some individual who doesn't exist in India (like Shahid Bilal). So how & who can they catch. So, there is no question of 'unsolved cases'. All the cases have been solved second day of incident, that's why our political leaders and security agencies personnel can sleep peacefully.
