Would The Boston Bombing Have Been OK If They Had Used A Drone?

Making a crockpot bomb and leaving it along the street during a marathon is a pretty shitty thing to do.  No doubt about that, but would it have been cool if the mad bomber had used a drone instead?  American military and CIA drones kill and mutilate all over the world just about every day, mostly for the protection of war profiteering and other corporate interests as opposed to the protection of American civilians or freedom or some other bullshit.  So, if by some miracle, another nation manages to access a trillion dollar military infrastructure and decides to sow a little chaos in the lower 48 by blasting away with some drones is that cool with us?  It's apparently cool with us when our government does that drone shit overseas, while the Boston crockpot bombs are the greatest atrocity in human history since 9/11.
