Personally, I reserve judgement on what actually happened at all these places because the facts are not completely in, and there is ambiguous information. It is nice to decide either way but I just don't think objectively we can do that.
Regarding them being patriots, I can see what wolfwood is getting at but I think the definition of a patriot is someone who takes action specifically for the betterment of the country and/or his/her peers. I don't feel these cult guys did that. Their main objective was not to make America better (e.g., I would argue that wolfwood is more of a patriot than Koresh, as he seems to be actively engaged in the legal battles to secure 2A for fellow citizens), but to run their own cult camps the way they like. They may be expressing their 1A and 2A for freedom of faith, speech, arms, etc. but they are not actively engaged in defending them. Depending on what you think you can say they are martyrs or victims of happenstance, but they are not patriots. If Koresh said to America, guys I am going to test the 1A and 2A by doing this, and you will see what happens. Then that might be different but just because he got shot up, doesn't pass muster.
I think the point that wolfwood raised is an interesting one, but I also agree the scenario outlined by KK is very valid (the officer arresting the drug dealer). It is not cut and dried. For example, what if we saw a Nazi about to shoot dead some Jewish children, and we were a German citizen (the Jewish children are also German citizens BTW). Maybe children is too obvious an example. Maybe if the Nazi was going to execute someone for simply muttering something negative about Hitler in public. What then? Not so clear cut.
