By keeping our eye to the microscope of relatively small crime such as this we remain oblivious to the bigger picture, i.e. why does our society spawn so many criminals? Is it the nature of a nation built on land theft and slavery? In Britain slavery was outlawed long before it was here, and the use of force to steal others lands and kill or displace its owners was reserved for the king. One little problem with asserting the equality of all men in a "land of opportunity" is that it gives license to ALL opportunists. 

Only by starting at the top down will we eliminate such sociopaths. You do not start by making the school-yard bully stand in the corner and hope to, by example, deter Obama from killing American citizens without trial or conviction, including a 15 y.o. boy whose only "crime" was going in search of his father. When those in power are held to the same standard we hold a street thug then and only then can we claim to have "justice for all." It's all connected and related.
