I’ve got no problem giving machine guns to kids. I’ve been on a range before where small children were very responsibly and very safely enjoying some full auto firearms (an H&K MP7A1, FYI), but what we see here is very different. Even for adults, machine guns can be difficult to control and need close supervision when firing them for the first time. In this case, someone thought it would be a grand idea to hand a full auto AK-47 to a 10 year old, not show them how to properly hold it, and filmed the whole thing. It was… cringey. The person filming the whole scene barely escaped perforation, which is either lucky or unfortunate depending on how you see things.
