Zimmerman also blatantly violated major principles of the Neighborhood Watch manual, ABC News has learned.





The manual, from the National Neighborhood Watch Program, states: "It should be emphasized to members that they do not possess police powers, and they shall not carry weapons or pursue vehicles. They should also be cautioned to alert police or deputies when encountering strange activity. Members should never confront suspicious persons who could be armed and dangerous...."





According to Chris Tutko, the director of the National Neighborhood Watch Program, there are about 22,000 registered watch groups nationwide, and Zimmerman was not part of a registered group -- another fact the police were not aware of at the time of the incident.
