Job of intelligence agencies is to train and send terrorists into a metropolis and shoot at laborers and commuters with a machine gun?
On your question about what Pakistanis should say - please do watch that programme Secret Pakistan. All those “suspicious” things started after American found out ISI/Pak military had been double dealing them. If ISI hadn;t done that CIA wouldn’t have to second guess or distrust PAk military. That is why I am saying all in Pakistan must watch that program so that everyone understands they are all being played by the military and getting killed in the process
