There are several witnesses to this shooting and the man accused of killing Jordan Davis at a Jacksonville, Fla., gas station was arrested almost immediately. In the Martin case, neighborhood watch volunteer George Zimmerman wasn't arrested until more than a month after the shooting.
Michael David Dunn faces a murder charge. Police say Dunn opened fire after telling Davis and his friends to turn down their music. Dunn's attorney says he shot in self-defense.
Davis' funeral will be held in his hometown of Atlanta on Saturday.
