Social media is not as limited as you think. Nowadays even drivers, peons and shopkeepers
(lower middle class) have Q Mobiles with Ufone internet on them. Yes, its obviously not as common as in the US but its still a lot.
Pakistani also has another form of "social media". SMSs chain messages. Seriously, those things spread like wildfire. That's how a lot of stuff (for example "Go Nawaz Go" campaign) spreads among Pakistanis who don't have internet. Practically everyone has some sort of SMS package.
Mentality is changing, information is everywhere. Slowly but surely, Pakistani society is changing for the better.
I disagree. There might not be any immediate change (I mean, you can't expect politicians to suddenly become humble servants of the public in one day), but its a powerful sign/symbol. It shows that people are no longer going to sit and believe whatever these people tell them, neither are they going to tolerate politicians' badmashi. People are waking up.
As for the allegations that those people were all PTI workers, it doesn't matter. It just doesn't matter. Someone comes late for a flight, you either send him back or put him on the next flight. You don't make 200 people wait for one guy. The passengers were right and the politicians wrong. End of story. It's especially shameful how instead of apologizing, Rehman Malik was trying to justify delaying the flight.
It doesn't matter if the plane was late "due to technical problems" and Rehman Malik just happened to arrive, he came late and since he is a human being and not superior to the other passengers, he should have been treated in the same way the others are.
