[2] Though White House, National Counterterrorism Center (NCTC), and CIA spokespeople have declined to comment on the database, officials have stated privately that kill lists will expand "for at least another decade", if not indefinitely.
The creation of the Disposition Matrix database is part of an effort embraced by White House counterterrorism adviser John O. Brennan to codify the targeted killing policies developed by President Barack Obama.
[8] Obama administration lawyers have asserted that U.S. citizens alleged to be members of Al Qaeda and said to pose an "imminent threat of violent attack" against the United States may be killed without judicial process.
[9] U.S. officials have described the Disposition Matrix as legally and morally sound, and The Washington Post has written that "internal doubts about the effectiveness of the drone campaign are almost nonexistent".
[2] U.S. officials speaking to The Washington Post seemed "confident that they have devised an approach that is so bureaucratically, legally and morally sound that future administrations will follow suit".
[1] Brennan, a principal architect of the "Disposition Matrix", stated in April 2012 that "in order to ensure that our counterterrorism operations involving the use of lethal force are legal, ethical, and wise, President Obama has demanded that we hold ourselves to the highest possible standards and processes".
[1][3] Robert M. Chesney has written for the Lawfare blog that "it certainly is a good thing to create an information management tool that makes certain that officials across agencies and departments can have real-time, comprehensive understanding of the options available (practically, legally, diplomatically, etc.)
[13][14] Anyone who thought U.S. targeted killing outside of armed conflict was a narrow, emergency-based exception to the requirement of due process before a death sentence is being proven conclusively wrong.
The American Civil Liberties Union (ACLU) has condemned the database, writing in a press release that "anyone who thought U.S. targeted killing outside of armed conflict was a narrow, emergency-based exception to the requirement of due process before a death sentence is being proven conclusively wrong".
[16] Greenwald concludes that the Disposition Matrix has established "simultaneously a surveillance state and a secretive, unaccountable judicial body that analyzes who you are and then decrees what should be done with you, how you should be "disposed" of, beyond the reach of any minimal accountability or transparency".
[16] Former counter-terrorism specialist and military intelligence officer Philip Giraldi has criticized the disposition matrix's "everyday" killing of targets with what he calls "little or no evidence", leaving the White House "completely unaccountable".
[3] Regarding the effect of the database in the United States, the site has written that "the Obama administration has arrogated to itself the most extreme power that can be asserted by any dictatorship—that of ordering citizens put to death without presenting charges against them, much less proving them in a court of law".
[22] In 2016, New York Daily News journalist Gersh Kuntzman has criticized the U.S. government's drone assassination program, and has even implied that the Obama administration may be guilty of war crimes.
[citation needed] Emmerson and Christof Heyns, UN Special Rapporteur on extrajudicial, summary or arbitrary executions, have described some U.S. drone attacks as war crimes.
[26][27] John Hudson, writing in The Atlantic Wire, has raised the concern that from a semantic perspective, the term "Disposition Matrix" sanitizes and perhaps obscures the more descriptive phrase "kill list".
