Is this hypocrisy?

3 BJP ministers of Karnataka who were caught on camera watching porn video on cellphone in the assembly, submitted their resignation with in hours of the scandal becoming public. CM had asked for their resignation after public pressure. Link

How easily these 3 ‘morally’ tainted ministers resigned? Compare this with the difficulty in getting resignation letters from Yeddy, Kalmadi, Raja etc who were not ‘morally’ tainted. Is there an element of moral policing in the way these ministers houses were stoned? Is this incident a victory or defeat for moral Police?
