Well, I really doubt that any political theorist would equate socialism with condoning cold-blooded murder. Socialist theory doesn't say anything at all about "give some to me because you're more wealthy." What it says is, "Each according to ability and each according to need." Families, for example, are the ultimate in socialist units: if one kid needs braces and the other doesn't, then one kid gets more of the family's dental fund spent on him. The baby still gets to eat, even though he doesn't bring in money from a paper route like the 12 yr-old does--both of them need to eat, even though one produces wealth and the other just lays there and sponges off the rest of the family in a cute and drooly fashion. That's what socialism is, at least in its purest theoretical form.
I imagine any Socialist with a true understanding of political theory would look at the perpetrators--who have the resources to have a ginormous 15-passenger van in running order, and look at the Billings--who have a large family with huge medical needs--and say that the Billings were, in fact, in greater need, and that therefore the greater distribution was just. A socialist would NOT say, give some to the criminal, nor would a socialist even recognize the steps that it took to equate one to the other. Robin Hood is a myth, and it's doubtful that any criminal who tries to use that as an excuse actually has any real understanding of Das Kapital.
I understand (I think) what you're trying to say about the criminal underworld and its justifications, but anyone who knows anything about socialism would likely place the criminal justification mindset and roots of class warfare (at least in the US) at the feet of Capitalism and its predecessor, the Puritan Work Ethic and the history of Calvinism--at least as much as they would socialism or any other political theory.
Of course, like any theory, socialism in it's "purest" theoretical form, and what big-S Socialism mutates into when practiced as a form of government, are two different things. Because whenever you bring humans and human self-interest into any theory or system, it all turns into one big Lord of the Flies. So I suppose in that sense, you're correct.
(Sorry to go off on a tangent there, but my particular pet peeve is when terms with a long and particular history get thrown around completely devoid of accurate context. Spent too many years correcting shallow grasps of theory on essays, I suppose.)
The guy linked to the Casey Anthony case was arrested and serving time somewhere around here in the Panhandle! Wasn't it in Okaloosa or Walton county?? Anyone remember?
