In an interview with Bill Moyers, journalist Glenn Greenwald criticized Americans' "warped perspective" on the U.S. government's use of unmanned attack ddrones, saying there's not much differenciating an American military drone strike from the Boston Marathon bombings.

"I don't think there is much difference," Greenwald said on Moyers & Company. "You could certainly say that one difference, and this is what people would typically say to defend what the United States does and to distinguish it, is that we are not deliberately killing civilians while the people in Boston did. And I'm not sure how true that is. There certainly are cases where the United States has very recklessly killed civilians."

But the use of drones, Greenwald continued, normally comes with a high probability of killing non-combatants in civilian spaces like a workplace or their own homes.

When Moyers pointed out that the columnist and former constitutional attorney's opinion ran counter to the findings of a March 2013 Gallup poll in which 65 percent of Americans said they supported the use of drones against suspected terrorists abroad, Greenwald responded by saying it pointed toward people believing the arguments put forth by President Barack Obama's administration.

"People have been inculcated to believe those falsehoods that the Obama administration has been propagating about drones, that they only target high-level terrorists," Greenwald said. "And when you combine that assumption, that false assumption with the invisibility of the victims, so that Americans never have to think about the human cost, both to the people we're killing and ultimately to themselves from the security threat that it produces, it's very easy to have a warped understanding of the cost of benefits it's deliberately inducing people to view these drone attacks in a much more favorable way than reality would suggest."
