I am not familiar with the Castle Doctrine. But all the Florida Stand Your Ground, for lack of a better word, says is if you are legally where you are, if attacked, you have no duty to retreat. The prisons of Florida are full of those who misinterpreted that. One cannot instigate the event then claim the protection of the law. I would the Castle Doctrine is something like that.
That reminds me of last year when the little guy with his gun who had a habit of confronting folks who took handicapped parking without a sticker confronted a black woman whod park in the blue spot and whose husband or baby daddy came out and confronted instigator and pushed him down
While down instigator pulled weapon and killed black man who was no longer pushing him or moving towards him in front of the soon to be dead mans nine year old son
They were looking at prosecuting him....dont know if they did
It all reminds me of what a friend of mine whod been in Vietnam later was a private security contractor overseas told me
A little scared guy with a gun will shoot you quicker than anyone ....if he looks scared dont confront further
I had an employee who did my deposits....nervous and was five seven and maybe 130.
Carrot a 9mm 92SB I bought him and I used to warn him dont shoot someone with my gun unless you really need to please...lol...
For the record I grew up in an era when men were men ans looked like we had ample testosterone with jaws and brows and chin and strong daily need for sex drives...and we fought...and when we got beat down....it was bad form to take your gun and kill your better for it
