George Zimmerman, the neighbourhood watch volunteer acquitted of homicide charges in the 2012 fatal shooting of unarmed 17-year-old Trayvon Martin in Central Florida, is suing Martin’s family, prosecutors and others involved in the case he claims rested on false evidence, according to a copy of the suit sent to the media Wednesday. Zimmerman is represented by Larry Klayman, a high-profile legal crusader tied to conservative causes and the founder of Judicial Watch before splitting with the activist group.
