He had every right to follow Martin; he had every right to ask if Martin lived there; and, he had every right not to be attacked. Not one of Zimmerman’s actions was illegal. Martin’s actions alone were illegal.
Tell it to the Grand Jury. My point is that the follower puts his SD standing at risk by his actions. If you want to have a slam-dunk, no questions, no nothing, walk free outcome, you don't do it by following "suspects" with a pistol.
If you do, don't be shocked if the Grand Jury returns an indictment.
It's what Mas Ayoob, the country's #1 expert on self defense shooting, calls "Problem #2."
Problem #1 being surviving a SD shooting, Problem #2 being, don't go to prison for it. There are things that while narrowly legal at a given moment in time (such as following a "suspect") might torpedo your later claim of SD in the eyes of the Grand Jury.
It sort of like this old ditty about the "right of way."
"Here lies the body of Jonathan Gray, who died defending his right of way.
"He was right, dead right, as he sailed along, But he was just as dead, as if he was wrong."
If Zimmerman winds up in prison, he will probably wish he had not followed Trayvon.
Yep...right on!
