Most Texans, let alone Californians fleeing high prices, don't have to worry about such things. Besides, the death penalty isn't exactly a negative if the alternative is life in (a Texas) prison.
Perhaps I'm alone in deriving small comfort in the knowledge that even if I were framed or otherwise unjustly convicted for the most atrocious of crimes, this would not be my fate (though the federal government showed in MA, for instance, with the Boston Marathon bomber, that they will override humane state law; you're never truly safe in the US). The knowledge that a gross miscarriage of justice could land me in "hell on earth" was troubling in CA (death row in TX and CA are quite different beasts on the other hand).
While our death row is an issue, you are something like ten to twenty thousand times more likely to die at the hands of our idiot drivers here in Texas. So keeping a sense of perspective is important.
