I don't really have an opinion on OP guilt, I'm interested in the evidence and what it tells us. I'm of the opinion that his story is a possibility but am open minded enough to know it can swing either way.
Truth be told,I've been surprised that everyone has been so adament of his guilt without giving him the benefit of the doubt, we have had similar shootings in SA (have posted the links) when the gunmen were treated with caution, sympathy and cases dismissed as tragic.
I can't fathom what's so different in this case. Yes, he is an idiot, egomanic, reckless and thinks he is a cowboy but doesn't make him a cold blooded killer. In fact, most who have met him have said he is a "all round nice guy". And if there was indeed an intruder in his bathroom, he would have been hailed a hero.
I guess I'm giving him the benefit of the doubt until the evidence proves otherwise. Ps: nice to "meet" you James
