Rants, Opinions, and Perspectives

I recently came across this rather interesting article in the Miami Herald: http://www.miamiherald.com/news/miami-dade/story/901828.html

Obviously (I think it's obvious at least), a convicted murder roaming the streets is not such a good thing, especially when the felon in question has escaped his just punishment. Assuming the two men mentioned in this article are guilty of the crime, your reaction is what?

Who is to blame for this? Is the justice system the actual problem? A defendant is guaranteed the right to a fair trial of course, so should this right change somehow? If the goal is to keep our society safe from both violent criminals and corrupt government officers (whether it be a police office, a district judge, a prosecuting attorney, a local mayor, etc.), can anything be done to ensure incidinces such as these do not occur again?
