Find me one armed force that hasn't killed innocent people
I could, possibly. However, it'd be much easier to find many armed organisations that do not TARGET civilians. And yes, planting bombs in commercial centres and what-not is considered targeting civilians targets. A stray shell from a cannon isn't.

I'll give you a clue, definately DON'T start looking at your own first.
Oh, but I always do. And no, I wouldn't want to get into THAT issue with someone that appearently supports terrorism.
