PETA isn’t the only group concerned about issues such as this. Personally, I don’t care who took the videos, I wouldn’t eat anything from this plant after seeing them.
I could point you to a number of sites that include interviews with people in the meat industry as well as rabbis and famous Jews who are incensed at the practices taped at Agriprocessors, but you’re a big girl, you look them up. I have a feeling you have another agenda going on here and I don’t want to get involved. No more with you on this topic.
I'm not going to do your research for you, but I can tell you this: there was never any problem with the kashrus at Agri. As I recall, PETA was shaking down Agri to give a six-figure salary to their "animal rights specialist" Temple Grandin.
