Yeah, thank God that the Chavez regime hasn't advanced to that level yet (like the Castro regime). But it will in time. Apparently she is being very careful about her whereabouts so I have confidence that she will be safe.
But it should also be noted that at this point Chavez doesn't need to kill his opponents. He only needs to imprison them and then cut off media coverage (like he has been doing). The next woman that he is currently targeting is María Corina Machado, the founder of Súmate (an election monitoring group). He has charged Machado with treason. In my opinion the underlying reason for that charge was because Machado received a meeting with President Bush in the Oval Office.
Now that Chavez has full dictatorial powers and media suppression laws already implemented he will be able to take his oppression to the next level. This is the point where it starts to get frightening.
The more dictatorial and violent Chavez gets the more the U.S. "progressives" will love him.
