I think that's a real possibility, but are you sure that it's settled? Have there been some post-Dennis cases clarifying that? In Dennis, while the Florida Supreme Court adopted the Peterson approach, it affirmed Dennis' conviction at trial. In its analysis, the Florida Supreme Court noted that Dennis presented his self defense claim at trial, and the jury found Dennis guilty beyond a reasonable doubt. There was no discussion of Dennis' degree of burden with regard to his presentation of his self defense claim. I think that you may be right, but I also see a possibility for perhaps some further refinement in Florida.
