Okay, first, stop with the moral disciplining in long useless words, come to the point. That just because he became billionaire in little time means something was fishy, because you know, clearly we haven't seen any such case at all anywhere around the world and such anomalies don't exist (sarcasm).
Still doesn't justify the fact that innocent people would be penalised for nothing, and no one didn't knew anything regarding that person, there were no cases on him at the given point in time, it's obvious with investment chances, people would take it. Let me give you a perspective, it's the equivalent of fining someone for buying from something from a shop because they didn't know that the product they bought was made through child labor. Sounds stupid, doesn't it? Exactly my point.
Also, kindly shut the **** up, if you think anyone who invested in Bahria Town is rich and made their livelihood through dubious means. You are clearly a retard for whom it's as simple as getting logged on some internet forum and typing 5 words classifies as the truth. Nobody knew he was corrupt or if there was any scandal when these schemes began. You saying that vast majority of those who invested in Bahria Town are rich and made their livelihood through dubious means just goes onto show how disconnected you are from reality.
