Here’s a little blurb from the Tempe, Arizona neighborhood watch program.

Neighborhood Watch leaves the responsibility for apprehension of criminals where it belongs—with the police.

Assuming it was a legitimate neighborhood watch program, wouldn’t Zimmerman have had to attend meetings where police informed him of this?

If Zimmerman was a watch captain, that would presume he had at least some level of responsibility in the organization. I can’t imagine he hadn’t been informed by police — likely multiple times — not to go out and chase down and confront alleged criminals.
