Don't think Huckabee had anything to do with that.
Read the record from Arkansas. The Huckster is directly the reason why this guy was on the streets. He commuted his sentence and set him free from a sentence of "life in prison w/o parole." And on top of the four murders of the police officers, the Huckster can also be rightly blamed for this perps other crimes, including rape of a child, assault on a Sheriff Deputy, etc.
Did you hear that, "DIRECTLY IMPLICATED" in all of these crimes!?
