The basic question, as I see it, is; do you trust your government. I would say no. Unscrupulous leaders have acted in less-than-honorable ways in the past and will likely do so in the future. The one redeeming fact of taking someone out with a drone strike is that it is highly visible, and therefore unlikely to remain unnoticed. If the government ever develops a drone capable of taking someone out without a large explosion, we are all in trouble.
