Unarmed Teenager Killed by White Neighborhood Watch Captain

Words can not describe the sadness I feel after recently hearing about a 17 year old teenager named Trayvon Martin, who was visiting his father and step-mother over school break, and returned home to his mother in a body bag. 

When police searched the unarmed teenager they found a bag of skittles and a can of ice tea, that he had bought from a corner store. The young man's killer wasn't arrested and instead was allowed to go home to continue on with his life, while a child that he purposely targeted and murdered lay dead in a morgue. 

Why isn't the killer arrested?! Where is the justice?!
