 And that's why I recommend to others in adult education, if you're teaching in a high-risk, high-liability area, in my case, the use of deadly force, but also teaching emergency medicine, emergency driving, things of that nature, have the key elements on video, not only so you can show, here's what I taught the student, but so that is there to educate the jury, to educate those who will judge your student when they do what you trained them to do.
