That video deeply angers any competent instructor. The situation was easily predictable and easily preventable. The instructor was to blame for not paying attention to basics, like assessing the ability of someone to handle recoil and keeping your hands where you can control the firearm if it something goes awry. Review the video and ask yourself "Why in the bloody hell does he have his hands in that position?" There's no good answer to the question especially for his left hand being under the gun. Why was he on her left? That one is slightly more forgivable but it's still wrong in that situation. At least the instructor's family has spoken out to help the girl recover. Unfortunately, they later came out for more controls but at least they are on the record as forgiving the girl.
