Some Believe That Anti-Terrorist Activities That Lead to Operational Excesses

Some believe that anti-terrorist activities that lead to operational excesses may nevertheless be morally justified under the principle of "double effect," meaning:

A) An unintended but unforeseen morally bad effect of an action can be excused if both the action and the intended effect are morally impermissible
B) An unintended but unforeseen morally bad effect of an action can be excused if both the action and the intended effect are morally permissible
C) The activities are morally permissible if they produce two effects, so long as one is morally permissible.
D) The activities are only morally impermissible if they produce two effects, both of which are morally impermissible
