the issue of karachi is not MQM thugs, the issue is the law and order, the police itself is the biggest mafia, karachi can't be peaceful till its police and law enforcement has willingness to solve the issue, only karachiites can solve their own issue, presently MQM has no police powers, no law enforcement, only MQM knows how to run this city, unfortunately the city is being run by those who are not stake holders and have no interest in solving karachi issues
karachi lays golden eggs, every political or non political criminal has interests in karachi, karachi has a huge black budget, 99% of it is non political
you can now figure out the rest
the version of karachi that the political thuggery is the main problem for karachi is a very naive analysis, 90% of the criminals in karachi central jail are not even the locals, they are all immigrants
