Sorry to say, Neither you nor me was there so how can we say "He didn't ask them to return the looted wealth or not to conspire with the enemies of the state". He's a scholar and IMO it is rightful thing to meet these kind of people to show them the right path. A common person can't reach there to guide these stooges and goones than why not a person who's influential ?
These vocal people have only one duty, to build public opinion. The moment he speaks against the corruption of Sharif family he has no entry in sharif palace and no air time on PTV.
