Like I been saying. Legally he had the right to shoot Trayvon and if the Jury would have found him guilty he would have appealed it and got it overturned. That trial was a dog and pony show. Stand your ground is basically a law that says if somebody makes you afraid in a confrontation you can legally kill them and its acceptable.
First of All, We don't know if legally he had the right to shoot Trayvon. No one knows what happened during the altercation. That was the problem with this case and the reason why it was a waste of time bringing it foward without the initial grand jury to see if there was a case against Zimmerman. I completely agree that the trial turned into a dog and pony show
Also Stand Your Ground had nothing to do with the Zimmerman case. Stand Your Ground only comes into play once you know definitively who started the altercation.
With your basic self defense in a criminal case, there is a duty to retreat before you can use any kind of force and be justified for it under the law.
Stand your ground is derivation of the Castle Doctrine which says that you have no duty to retreat if you are attacked in your home. Stand Your Ground brings the Castle Doctrine to the outside of one's home
Stand Your Ground basically is that there is no duty to retreat once someone starts an altercation with you anywhere. You can use deadly force only when someone starts a fight and you are scared the other person may kill you.
The Judge usually determines according to the fact whther this is a stand your ground case and can dismiss the case. The Defense in this case did not bother to have a Stand Your Ground hearing with the judge because there was no solid facts to determine what happended in the altercation for the judge to make a decision.
