Deeply flawed exit/entry control system of Pak

Everyone is familiar with Pakistan’s so called “Exit control List”, but the sad part of this list is that we are using it for pure political vendetta.

If not then how can one explain that Jihadis from UK, Islamists from US and all those terrorists from arab lands can come and go without even a minor check by our embassies, immigration and customs officers?

Sure we should NAB the corrupt officials like this Malik character, but why on earth our eyes are shut towards the Islamists?
