one thing I'd watch out for, though, are jump cuts. (although, from the scale of the prank I don't think that matters.)
for example, this quote:
"yeah, they haven't quite developed, uh, <CUT>, what we call conscience, where you feel guilty about doing something wrong, that's developing, you're learning right and wrong. <CUT> if they haven't developed that yet, they can be very effective soldiers."
that's potentially a pretty horrifying thing to say, but with the cuts, it's hard to know if that's really how it was said. it doesn't sound obviously edited though, so maybe it's just camera switches, I'm not an expert at detecting that kind of thing.
Ihey had a man with guns with puppets on them telling kids to feed the puppet bullets
