Who is responsible to stop these killings?

Sindh Government with out any doubt. Both, federal and provincial governments have failed to provide any peace in Karachi. Whether they are target killings or criminal killings the government is responsible to provide protection to civilians of their life and property. Apparently, nothing is happening to stop this bloodshed.  It seems this bloodshed has been accepted as a norm.

Nobody is doing anything. Our men of opinion once in a while speak out but nothing more than that. Ordinary citizens are already demoralized.  Supreme Court also conducted a session here in Karachi without any benefit. Just show business. Our TV channels only give us the news how many people got killed in Karachi during the last 24 hours. There should have been a concerted effort to put pressure on the government to do something to stop this bloodshed. Nothing happened.
So what we should do?

The only solution left is to bring the Army to clean out this mess. We don’t see any other way to protect the human lives. Some people say Army may be successful to stop this bloodshed then what after that. Let us stop the loss of human lives then again it will be the responsibility of the political government to maintain the law and order in the city.
