In the early 1970s, I spent two summers slinging pork loins in a Chicago meat-packing factory. Rose Packing Company paid a handful of college students $2.25 an hour to process pork. Donning combat boots, yellow rubber aprons, goggles, hairnets and floor-length white smocks that didn't stay white very long, we'd arrive on the factory floor.

The actual killing seems distant, almost unnoticeable, and we grow so accustomed to our remote roles that we hardly notice the rising antagonism caused by U.S. aerial attacks, using remotely piloted drones. The drones fire missiles and drop bombs that incinerate people in the targeted area, many of them civilians whose only "crime" is to be living with their family.

Villagers in Afghanistan and Pakistan have little voice in the court of U.S. public opinion and no voice whatsoever in U.S. courts of law. Aiming to raise concern over U.S. usage of drones for targeted killings, 14 of us have been preparing for a trial here in Las Vegas, where we are charged under Nevada state law with having trespassed at Creech Air Force Base, in nearby Indian Springs, Nevada.

The charges stem from an April, 2009, action when several dozen people held vigils at the main gate to Creech AFB for ten days. One of our banners said, "Ground the Drones, Lest Ye Reap the Whirlwind." Franciscan priest Jerry Zawada's sign said: "The drones don't hear the groans of the people on the ground, -- and neither do we." Jerry carried that sign onto the base on April 9, 2009, when 14 of us attempted to deliver several letters to the base commander, Colonel Chambliss.

Nevada state authorities charged us with trespass. We believed that international law, which clearly prohibits targeted assassinations, obliged us to prevent drone strikes. "It is incumbent on pilots, whether remote or not, to ensure that a commander's assessment of the legality of a proposed strike is borne out by visual confirmation," writes Philip Alston, the UN Special Rapporteur on extrajudicial, summary or arbitrary executions, "and that the target is in fact lawful, and that the requirements of necessity, proportionality, and discrimination are met."

The United States isn't at war with Pakistan. U.S. leaders repeatedly stress that Pakistan is our ally. Nevertheless, U.S. operated drones are used for targeted killing in North and South Waziristan. "Targeted killing is the most coercive tactic employed in the war on terrorism," according to the Harvard Journal. "Unlike detention or interrogation, it is not designed to capture the terrorist, monitor his or her actions, or extract information; simply put, it is designed to eliminate the terrorist."

The Pentagon claims that the drone attacks are an ideal strategy for eliminating al Qaeda members. Yet in the name of bolstering security for U.S. people, the U.S. is institutionalizing assassination as a valid policy. Does this make us safer?

General Petraeus may perceive short-term gains, but in the long run it's likely that the drone attacks, as well as the night raids and death squad tactics, will cause blowback. What's more, drone proliferation among many countries will lessen security for people in the U.S. and throughout the world.

With the usage of drones, the U.S. populace can experience even greater distance and less accountability because U.S. armed forces and CIA agents, invisible to the U.S. populace, can assassinate targets without ever leaving a U.S. base. Corporations that manufacture the drones and technicians who design them celebrate cutting edge technology and rising profits.

In a Las Vegas courtroom, on Sept. 14, the judge who hears our case has an unusual opportunity to help accelerate that process by allowing expert witnesses to speak about citizen obligations under international law and our protected rights under the constitution of the U.S., all in relation to our duty to abolish drone warfare.
