Also the after action as well. My thing is to keep my mouth shut. Just name and "I will give a statement after I have spoke to an attorney:" and that's it. Masaad Ayoob states to give details to the cops like witnesses or evidence, because they may miss something. IDK how much chatter box I will be after a high stress situation, so talking about what Ayoob recommends, may open to providing more details than needed., IMO.
Back of my USCCA card states to say "I was attacked, feared for my life and had to defend myself". But in Hawaii, deadly force can also be used for kidnapping, rape or sodomy. So if you make that statement but was about to be raped or sodomized, it wont look too good.
