My take. A small town in Florida had an incident last year. It seems a neighborhood watch guy, who is Hispanic, saw someone he didn't know in his gated community. Due to a number of robberies in the housing tract, he called the police for advice and minutes later was confronted by this outsider. A scuffle ensued and the Hispanic guy, fearing for his life, shot and killed his attacker who turned out to be a black teenager. Florida law said he was within his rights to defend himself and no charges were filed.
