One of the inmates, Aly, got right up into one of the kid's face and showed them that he got his eye stabbed because he thought that he was smarter than everyone.
The documentary, being a repeat of the 1978 documentary, superimposed onto an aftermath documentary, by Danny Glover, is hard R in all moments, with its educational value, being the only reason this is not R-rated/TV-MA officially. But this is not for kids to watch alone. UPN, which aired this particular follow-up, had the distinction of being cutting edge, which is why it was more popular than The WB (and more Warner Bros.ish too).
