Sir: We know a man who used to be the president of Pakistan. Unlike the late president of India (who died with virtually nothing in his name), ours has property in Pakistan as well as in other countries. He has enough money to live in foreign lands, his children are able to travel without being bothered about how their father got so much wealth, and the Federal Bureau of Revenue (FBR) has never asked him about the source of his income. Why is the National Accountability Bureau (NAB) not doing anything? Why is the apex court not taking suo motu notice?SHAKIR LAKHANIKarachi
