Zimmerman created the situation. I agree with this.. However, when Martin double back to confront Zimmerman he then became the aggressor. Neither man is a hero in this situation, but from a legal standpoint, there was no reason to Zim in jail. He was defending himself....or so the evidence shows. Case closed.
Mr. Zimmerman, in his role as captain of the Neighborhood Watch and as a homeowner, resident, citizen and taxpayer, was well within his rights to observe and report on a suspicious person, especially with hundreds of break-ins, burglaries and other crimes committed within the past few years in his community.
