I read this and became sad. Of course, since all we know at the moment is that (a) the guy was a census worker; and (b) he was found with the word "Fed" written on his body, we have no way of knowing what was up. The kind of speculation I have read both at the Freeper site and on Facebook from both ends of the spectrum is meaningless.
The guy was lynched, pure and simple. Maybe by a nutter of the political variety, maybe by a meth-head (as common as fleas on a dog in most rural areas). Either way, right now, it's enough to just say that any murder is filled with sorrow.
