My whole opinion of the Treyvon Martin case is that Race should be a none issue.
A young man was killed by another man who admitted as such. Based on this information alone the killing should investigated thoroughly and the man who killed Treyvon should held in custody. In any other democratic country in the world Zimmerman would have been held in custody pending pre trial and based on what has been reported so far would then face trial.
An interesting point to be taken from this case is that during a channel 4 (a British TV station) interview with Treyvon's family his father stated that he does not believe his son's killing was race related and only demanded that the killing be investigated properly by law enforcement.
