Please don't do this. Not because I don't think you (random psychiatrist on the internet) would do a bad job (I don't know you), but because you are obviously in way over your head. I say this from the perspective as someone who had the bare minimum forensic exposure in residency, then went to work in a forensic setting (not in a forensic capacity, though -- just providing clinical care to pts under forensic commitment), and I had no idea how much I didn't know. It took me a solid year to feel like I had any idea what the heck was going on legally/forensically, what the different types of court testimony entailed, which types of hearings would be easier vs more difficult for me and why, etc. [edit: and I had a lot of supervisory and administrative support, a lot of people wanted me to have a good experience and stick around. Without this, it would have been a nightmare.]
Please ask yourself, do you really need this in your life? Do you want it in your life? If so, is there a less risky way to dip a toe in it, like starting with some CMEs, going to a conference, finding a mentor of some sort...
