Compare and Contrast: Killings in Kansas and Arkansas

There's been a lot of discussion, primarily on conservative blogs, about the different reactions to the Tiller assassination and the Little Rock Army-Navy Recruitment Office attack which killed Private William Long. Most of the discussion is based on a logical fallacy: that one must be entirely consistent in one's condemnations to be taken entirely seriously on any of them. "But what about..." is a classic rhetorical tactic, shifting the grounds of an argument and sometimes derailing it entirely.

That said, though, I'm largely in agreement that all violence needs to be taken seriously -- I'm a procedural liberal who thinks that political processes need to be settled by political and legal means, and I want to be protected when I make unpopular stands.

Still, I think there's a reasonable question: what, if anything, are the differences between these cases that might explain different reactions? Some of this is, clearly, speculative, as we haven't gotten the full details on either (alleged? Seems unnecessary) killer yet, but I'm working from the information available.

First, the similarities:

1. unmistakeably violent murders, illegal acts
   
2. May 2009
   
3. used legal firearms
   
4. apparent religious motivation
5. clear political motivation
6. perpetrator seems to believe they are acting in defense of the innocent
   
7. victim was a firm believer in their cause
   
8. individual perpetrators without organizational support, no conspiracy
   
9. targetting respected social institutions (medicine, the military)
   
10. targets demonized by political partisans, in long-running, public and intense disputes

I may be overstating some of the similarities, but the parallels are strong, nonetheless. Now, the differences:

1. abortion rights v. the military
   
2. civilian v. military victim
   
3. handgun v. assault rifle
4. individual target v. institutional target
5. individual target v. potential mass casualties
   
6. mission-critical individual v. low-ranking support staff (or, to put it another way, tactical v. symbolic)
7. high-profile target v. previously anonymous victim
   
8. domestic policy v. foreign policy
9. at church v. at work
10. older family man v. younger unmarried
    

The conservative charge of hypocrisy is based on the assumption that difference #1 is the critical one, really the only one. But it's #6 and #7, I think, which actually drive media coverage: the immediate effects of these deaths are different, as are the likely long-term effects. To a large extent, I'd say that #8, because it directly impacts more people's lives locally, and #2 also, are significant factors. Not to downplay the tragic death of this member of the military, but it is an occupation in which violent death in the line of duty is less shocking.

My final thought is one which others have also made. Given the parallels between the cases, why have so many prominent conservative voices failed to call the Tiller assassination an act of domestic terrorism, and to address the implications of that for domestic politics?
