You're just getting the usual liberal rule-of-law stuff. "Wring, wring", as you say. People worrying about their moral bank accounts and all that.
There are other ways of looking at the situation -- as you do above. If you extend the logic a little, you can see a process of demoralization going on, where, gradually, more and more dubious acts become acceptable, with each act rendering the next step more feasible. Demoralization is a form of social degeneration in which a community gradually loses the rules or principles which bind it together. The end result, assuming the process isn't arrested, is a moral collapse in which the members of the community can no longer maintain it as a coherent social entity; something like civil war or a coup d'etat is likely to follow. Personally, while I can see the historical grandeur of it all, I'm not looking forward to participating in it, and I'm wondering if there's some place I can hide out. Probably not, eh?
I know this will seem hard to believe of good old America, but think about it. A for-instance may help.
1. It's okay to kill some guys in a car in Yemen with a rocket because you suspect them of being members of Al-Qaeda.
2. It's okay to kill some guys in a car in Germany with a rocket because you suspect them of being members of Al-Qaeda.
3. It's okay to kill some guys in a car in Tennessee with a rocket because you suspect them of being members of Al-Qaeda.
-- that sort of thing; see what I mean? Everyone can play; locale isn't the only term you might vary.
