The story is indeed tragic.
It is only tragic that a guy who needed to use self-defense has been savage for weeks in the court of public opinion and had a bounty put on his head by black thug racists demanding he be arrested because he had to shoot a young black punk who decided to re-engage and start beating the sh1t out of Zimmerman.
It I tragic for Zimmerman, not Trayvon. Normal civil people do not do what he did and believe that is an acceptable way to behave towards others.
