"Concerned citizen" Sean Pearce uses binoculars to scan along the US/Mexico border west of Douglass, Arizona April 3, 2005. Pearce, who had the day off from work, joined Minuteman volunteers who are manning observation posts around the clock this month along the border in eastern part Arizona, to bring attention to the number of illegal immigrants coming north from Mexico. Pearce, who works as a sheriffs deputy, said he was shot twice in the abdomen by an illegal immigrant who was involved in a murder case he was working on. REUTERS/Fred Greaves FG
