Do you think NDA/UPA govt can catch Dawood? don't even think of it......If the Govt of India is not able to demolish the illegal property of him without his approval then thinking of arresting him is insane.
better demolish all of them or modify them to Public toilets under Municipal control for its cleanliness. But Govt. should have guts and the Judiciary too for ordering its demolition and converting them to Toilets for slum dwellers and other needy Public.
