shit happens
You consider the murder of innocent people "shit" ? As if bombing people from unmanned aircraft and "accidentally" killing innocent people is acceptable in any way?
The problem is that the alternative to drones is a land invasion and slaughter of the "guilty." Even assuming the "guilty" (using scare quotes as the war on terror is mostly bullshit) are killed, a few 10s of 1000s of innocents would die as the marines fought their way there.
