Orange Polo or Orange Jumpsuit?

So I have been reading and hearing alot about the kid from Florida named Treyvon that got shot and killed. From my understanding, the shooter (Zimmerman), who was the neighborhood watch leader, called the cops when he saw the victim (Treyvon) walking around his neighborhood at night. Zimmerman then went after Treyvon on foot even after the police told him not to. When Zimmerman eventually catches up to Treyvon there is a scuffle and Treyvon gets shot and killed. Treyvon was unarmed. On the 911 calls made that night from the neighborhood you can hear someone screaming "HELP". At first I thought well he was this poor innocent guy and Zimmerman was on a power trip and killed him. But, then a witness surfaced saying that Treyvon was beating Zimmerman to a pulp and that Zimmermand shot him in self defense. Then I  start seeing the real pictures of Treyvon and Zimmerman and I think to myself maybe the media was being a bit biased on this case. The first pictures I saw showed a closeup of a not so happy Zimmerman in an orange shirt that at first glance makes you think of an orange jumpsuit from prison. The first picture of Treyvon was a young cute  boy smiling and wearing a Hollister shirt and it makes you think poor kid, hes wearing Hollister he can do no wrong. Then I saw the more recent pictures of the two guys. Zimmerman smiling in a suit and tie. When I looked at the other picture I noticed that they had zoomed in so far that you couldn't tell what he was wearing, you just saw the orange and it made you think prison, but it could have been a collared shirt or whatever. Anyway, the second picture of Treyvon was of a shirtless guy sagging his pants and flipping the bird. So I dont know what happened that night; was it in self defense or was a guy on a gun toting power trip? What I do know is I feel pretty foolish because I fell for the medias biased portrayal of two men and now I dont know what to believe. It kind of makes me not want to watch the news because I feel like I am being led like a sheep or something.
