This whole fucking episode pinpoints everything wrong with Beyond Scared Straight tbh.
These kinds of programs do nothing to help at risk kids and only exist to intimidate youth into passive conformity. It enables police brutality, psychological and physical trauma, and does nothing to actually solve issues these kids are facing. Even in the episode the pigs admit they break down these kids first so they can more easily dictate them. It's repeated evidence of the Stanford Prison experiment and how positions like prison guards and cops are filled by sadistic pieces of shit.
