I will try to explain. There are many who are beneficiary of PML-N and PPP being at helm. For instance, why you think number of people come in support of Saad Rafiq? Some fool will say its because NS and PML-N has civilian power, hogwash. Saad Rafiq told people that vote me and and when I become minister, then will make sure all those who voted me will get employment. Thus there are thousands of employees Railway has who never show up at work but collect salary at every month. Naturally, when Saad and his brother was thrown behind bar then all these employees will have problem, because they were also beneficiary of his corruption, therefore, they came to protest.
