Lol multitool. He legally owned a knife. He did not legally stab someone. Stand your ground has always been extremely nuanced and response has to be proportional AND they found that he instigated it. You want me to be able to bring my “legally owned multitool” to a bar and then stab anyone who bumps into me?
Mental health isn't some excuse, it offers us some explanation to why you might do crazy shit, but you have to be extremely fucked up in the head for it to matter at all legally, and even then the best you might get out of doing so is marginally better food in exchange for a longer sentence.
