All great people have lived in jail some time or the other. Lord Krishna was born in a jail, mahatma Gandhi, Pandit Nehru, Bal Gangadhar Tilak, Maulana Azad, Bhagat Singh, Napoleon Bonaparte, Joan of Arc- they all have stayed in Jail.
The only difference here is that the "Honourable" MPs mentioned here dont have as hounourable reasons to be in Jail.
