I think the brief is frivolous from the start because of improper citation of Florida Rule of Criminal Procedure
3.580. But it's amusing to note what are, in my opinion, its other errors.
The brief ignores the word 'independent' in 'independent forcible felony' (pp. 1-2).
The trial court ruled there was not sufficient evidence for an aggressor instruction, after hearing argument from both parties. The brief cites no grounds for revisiting the question (p. 2).
The brief misreads Florida Rule of Criminal Procedure 3.600(a)(2) [p. 178], by failing to read it in light of Rule 3.580 (p. 176). It ignores Rule 3.600(b)(7) [p. 178] (p. 2 of the brief).
