Why not? That is my point - the CIA and US military-intelligence complex has a history of acting as 'rogues' on the international stage, with catastrophic results for the regions they have played the 'rogue' in.
The CIA has done much the same in South Asia, as we can see now.
Davis did not have 'blanket diplomatic immunity' - he was attached to the US consulate, not the US Embassy, a fact admitted by the US Embassy itself in the initial days, before it changed its story. Davis's presence and residence in Lahore, rather than Islamabad, supports that position.
This is an example of the 'propagation of lies, distortions and smear campaigns against Pakistan' that the 'operative political reality in D.C' needs to change from.
