PHOENIX — By now, the scene is familiar: Two men who don't know each other get into an altercation — one black, one Hispanic. One has a handgun and shoots the other dead.
The victim is unarmed. The shooter claims self-defense and walks free. For more than a month, the victim's family waits to see whether authorities will file charges against the shooter.
Phoenix shooting has echoes of Trayvon Martin case
