If it was me, the first step, I would bring down all the businessmen who try supporting them in any way, state has that authority and power. Their place of business, shops, retail outlets, property advising offices whatever they are doing would be sealed, confiscated and forever locked down, bank accounts attached, school/college/university admissions refused, restrictions on their movement, forever ban on obtaining a passport. The supporters will have to pay heavy fines and keep appearing before the courts for rest of their lives. I will bankrupt them totally.
Then I will see how this crazy loony loon survives a day without free food, halwa and chicken ki daighay. Each one of the person present in his protests would face school/college/university bans for their children, refused bank accounts, and their Ids marked in NADRA's database. I would even go to the extent to refuse marriage certificates and nikkah nama registrations for their children ........... it's simple unless you make them feel and hurt each one of them individually ...... they won't understand.
