Arch, I understand it was put in place to benefit law-abiding citizens, but FL's SYG does have broad license from what I have been reading in cases. (I have also been reading cases in Texas and NV).
My State has the Castle Doctrine which I love, because it protects us from harm while on our property (excluding domestic violence w/o Rest.Orders).

To answer your question if I was on the jury, I do understand I am duty bound to only judge by the evidence before me and not vote with my heart. I would not dishonor the honor, even if it killed my heart.
(but I am too subjective on it, so I know I would have been excused/ not seated).
I am though a bit surprised how many people are directing their rage against White people - white women in particular - while the prosecution bears no responsibility? This was a crime on a Black man, by a Brown man, but it's White women's fault?
The truth is, Florida have some wild laws... From Terry Shiavo (whose husband should have been tried for causing her brain damage, imo), to baby Caylee Anthony, to now Trayvon. I would not want to a victim there, they don't seem to get much justice the way their laws are arranged.
