What is the reasonable additional cost in lives of citizens in order to capture a Bin Laden type terrorist alive, hold a public trial, and presumably sentence him to life in prison? Taking someone like that out with a bullet or a drone is much less risky operationally. They also avoid the additional geopolitical complexity of needing occupying forces in the relevant country. Maybe there should be some pre-operation due process rights, but it seems callous in other ways to insist on non-violence in all cases. Especially in response to catastrophic violence.
