Huckabee was very aware of what kind of Russian Roulette game he was playing by letting these turds out on the street. But why should he care, he and his family was always protected in some way. By where they lived, where they went to school, where they worked or by their own private or public security people.
People that attain high office like Huckabee and others will continue to let bad guys out to harm more people until the day that one of the bad guys finally gets to someone like Huckabee and does what this guy did to those poor police officers. If that ever happens then this kind of thing will stop.
