I do my best to keep abreast of cases nationwide, especially those "high profile" cases.  One case in particular that has had me curious for many years is that case coined "The West Memphis 3". For the majority of my adult life, I've worked in the Criminal Justice System.  I've had the benefit of working for both the Police (prosecution) and the Defense (Public Defenders Office) and now as a private consultant for both sides of the system.   This has given me an even greater knowledge and understanding of our Judicial System.  Although I've always believed in fairness, and that you are considered "innocent until proven guilty", I have had several experiences that this just didn't ring true.  The case in West Memphis is such a case, in my opinion.  It's filled with poor investigating and corruption.  I was planning on writing a piece today on that case, but soon realized that I could not do it "justice".  For that reason, I decided to add a couple of links so that anyone interested could read about the case for your self.  Believe me, there is plenty of information out there about this case and I'm sure you will find the story of the case intriguing.  Enjoy.

We've all heard the expression "the glass is half empty" or "the glass is half full".  This is a common expression, "used rhetorically to indicate that a particular situation could be a cause for optimism (half full) or pessimism (half empty); or as a general litmus test to simply determine an individual's worldview. The purpose of the question is to demonstrate that the situation may be seen in different ways depending on one's point of view and that there may be opportunity in the situation as well as trouble". 
Perception is defined as "the process by which an organism detects and interprets information from the external world by means of the sensory receptors".  Of course, everyone has the ability to see things, or perceive things, differently than others.
