Consider the documentaries about the livestock industry that present these operations as they are supposed to operate, and the disgust that they evoke in viewers. Now consider if that footage was much more available. I see two possible outcomes. Either people see that and realise where their meat is coming from, and elect to eat less/no meat, or people become desensitized to the conditions, and the leaked PETA-style footage becomes less apalling. The former possibility makes this idea unrealistic in practice, and the latter doesn't seem very good either.
