ATM Robberies are not new crime in Karachi. In Past many videos were released, of ATM robbiers in Karachi. You can that videos here http://naumankapakistan.blogspot.com/2009/04/another-atm-robbery-in-karachi-pakistan.html
The government of Pakistan, and Local government in Karachi failed to stop these robberies. The police of Karachi always says that crime rate in Karachi is under-control. But the killing of the Ghulam Nabi in ATM shows that the reality is different.
Recently many innocent people were killed in Karachi due to target killings. But the Government of Sindh and their alliences are fighting for the seats or hold in Karachi. All are blaming each other for these target killings. But the reality is that in these target killings, always a poor man dies.
