Kent Holder, a volunteer with Fox Island Citizens' Patrol, poses for a portrait for Reuters on Fox Island, Washington July 27, 2013. In Holder's view, George Zimmerman violated two basic tenets of the watch program: Never confront a person you perceive to be suspicious, and never carry a weapon while on duty. Last weekend, a Florida jury acquitted Zimmerman of second-degree murder and manslaughter charges in the 2012 shooting death of Trayvon Martin, who was unarmed, in Sanford, Florida. The case has focused fresh attention on the civilian patrols by law enforcement and trainers. Picture taken July 27, 2013. REUTERS/David Ryder (UNITED STATES - Tags: CRIME LAW)
