Regarding the use of vitriolic words/phrases: Pardon my stupidity, but where does it say that the shooter was attributing anything he did to Sarah Palin, talk radio shows, or any of that drivel?
I seem to be missing that part somewhere.
Until shown to me, I go with the position that these things have not been proven to have encouraged the shooter; thus, the outcry against the "vitriol" being purported as a cause for this heinous crime is more of a smoke screen to further an agenda to silence people, rather than focusing on the actual cause and perpetrator of the crime.
Again, if someone can show the article(s) that indicate the shooter was a fan of, much less implementing anything said by, Sarah Palin or the right (or left) wing talk show hosts, then I'll retract my statement above.
