"Even if the U.S. gives us $10 million or $20 million, can my son come back?" the father of one of the victims said then. "This will be selling my son's blood which will be like deceiving the people and government... If we accept money, this will give them a way and they will keep killing people and paying money and thereby Pakistan will be sold and will be finished."
Under a pair of Pakistani statutes known as Qisas and Diyat, those accused of a crime, even major ones, may be set free without trial if they can produce acceptable compensation to the victim or the victim's family, said Pakistani law expert Paula Newberg of the Institute for the Study of Diplomacy at the Edmund A. Walsh School of Foreign Service.
But, Newberg said, those laws are about compensation, not justice.
"In the current instance, it may be a way of removing Mr. Davis from the country," she said. "[But] as a mode of solving this kind of problem, it has the potential to set a very fuzzy precedent that does not meet the standards for justice in Pakistan or in the U.S."
