Why?

News coming across the wire this morning described how the police in North Carolina have shot and killed the serial killer who had been tormenting that state. Now, make no mistake about my personal view on this issue; I couldn't be more pleased that this low life is off the map. But the question we should ALL be asking is: "Why, with a rap sheet that is 25 pages long, was this creature allowed to be released from prison, to begin with?" All the deaths that resulted from this killer being on the loose can be blamed on the system, or should I say the lack of it! (Note to readers: The killer's name was purposely omitted, as per my policy of not promoting their agenda.)
