^ besides the point. movement in your country should be a right, not an evasion of law-enforcement.
the rights you have as an illegal immigrant type person unwelcome by the authorities and as a citizen exercising right of free movement are very different.
blah blah blah prove to me if there has been a single IDP who was sent back or barred from entering Punjab. In Karachi however, thanks to the MQM a task force of special police has been commissioned by ishrat-ul-ibaad (presidential commando MQM) to prevent them, and keep in mind a VERY SMALL percentage of the total refugees would travel all the way to Karachi, because its FAR away and costs money and the logistics does not suit them, especially if they want to return to their home cities. Like it or not, the MQM is giving the whole city of Karachi a bad name with this ethnic chirade.
