The president cannot lawfully order the killing of anyone, except according to the Constitution and federal law. Under the Constitution, he can only order killing using the military when the U.S. has been attacked or when an attack is so imminent that delay would cost innocent lives. He can also order killing using the military in pursuit of a declaration of war enacted by Congress.
Obama has argued that he can kill Americans whose deaths he believes will keep us all safer, without any due process whatsoever. No law authorizes that. His attorney general has argued that the president’s careful consideration of each target and the narrow use of deadly force are an adequate and constitutional substitute for due process. No court has ever approved that. And his national security adviser has argued that the use of drones is humane since they are “surgical” and only kill their targets. We know that is incorrect, as the folks who monitor all this say that 11 percent to 17 percent of the 2,300 drone-caused deaths have been those of innocent bystanders.
Did you consent to a government that can kill whom it wishes? How about one that plays tricks on federal judges? How long will it be before the presidential killing comes home?
