No, he wasn't within his rights, because even if Zimmerman were actually stalking him, that isn't an imminent use of force. I realize that people can feel threatened if someone is following them around, but that doesn't give them the right to turn around and attack the person following them. And that's what you're claiming here.
You apparently didnt read the law on self defense, in an attempt to remain willfully ignorant. But I will pull it for you again since you appear incapable of doing anything independently. http://www.husseinandwebber.com/florida-law-self-defense-use-of-force.htmlSelf Defense in Florida: When is Non-Deadly Force Allowed?
Under Section 776.012, Florida Statutes (Florida’s “Stand Your Ground” Law), a person is justified in the use of non-deadly force in self-defense where the person reasonably believes that such conduct is necessary to defend himself or herself or another against such other’s imminent use of unlawful force. There is no duty to retreat.http://www.leg.state.fl.us/Statutes/index.cfm?App_mode=Display_Statute&Search_String=&URL=0700-0799/0776/Sections/0776.012.htmlUse of force in defense of person.—A person is justified in using force, except deadly force, against another when and to the extent that the person reasonably believes that such conduct is necessary to defend himself or herself or another against the other’s imminent use of unlawful force.
As I stated before, Martin was well within his right to use self defense, your blood thirst for young kids not-withstanding. There you have the law, will you stop your pattern of ignorance and dishonesty and recognize the kid's right to defend himself. I will not go further with your ignorance until you acknowledge that.
