1. If the government has evidence that an American citizen is plotting an attack and knows where they are to attack them with a drone, why not arrest him? If the evidence isn't strong enough for an arrest, how can you condone a killing?
2. If the government suspected McVeigh and Nichols of bombing the federal building in OKC, would it have been OK to take them out with so-so evidence instead of arresting them?
The welfare of humanity is always the alibi of tyrants
