Here is an extract from the history forming the background to the still on-going manipulation of Middle Eastern nations by Western powers. The name of the person central to the Lockerbie investigation is redacted.
"The date of the finding of the Hayes green fragment lay well within the time frame of *******'s career with the CIA. And in the eventual trial of the two Libyan suspects, evidence given by DEA agent Louis Sherrow would prove that at the time of the Lockerbie bombing, the CIA had in their possession at least one identical MST-13 timer brought from Africa.
Furthermore, the publication of a set of declassified White House Emails would reveal *****’s long list of covert activities in the case of the Iran-Contra campaign. He would also be proved to have worked alongside colleagues for whom the creation of false trails and even the manufacture of evidence was an understood tactic.
An example of this is contained in a secret email written on 30th January 1986 by career navy officer James Stark, at that time attached to the National Security Council, and a working colleague of *******. The email was addressed to Admiral John Poindexter and to Howard Teicher, also working colleagues of *******. Stark looked at opportunities that had popped up in connection with destabilising the People's Democratic Republic of Yemen (PDRY). The subject of the memo was "PDRY Opportunities".
Given the nature of the Soviets, we ought to be able to find a great deal of actual evidence, which can simply be artfully exploited, and may thus completely avoid the more dangerous course of altering or manufacturing evidence." 
Thus the truth. We don't need altered or manufactured evidence on this occasion. But if we have to, we will.
