Oh no far from it it was in context, he meant what he originally said (before he lied about what he said and then apologized for what he originaly said).
Not that getting rid of crazy Chavez is a bad thing. Should have just stuck to his guns, now he just looks like a loon.
By out of context, I mean that he clearly did not spontaneously call for Chavez's assassination. Chavez is the one that started that line. More than anything, Roberts just agreed.
