By the way, the announcer annoys me; thanks for over-dramatising!
Anyway, the cruelty is sad, but cows are able to cope with a lot of abuse. Does this mean they should receive it? God no. However, animal abuse will always happen, just like murder, rape and stalking. Considering the amount of pain the cows probably received, I probably wouldn't say this is close to the worse animal abuse material I've seen. I will admit it doesn't justify it, but disgusting? I consider it wrong, but very far from disgusting. Partly because cows can take a lot of physical abuse due to how built they are (come on, they were being stabbed with pitchforks and weren't too physically injured).
I think deviance will always happen in the workplace, let that workplace be in Iraq, an office or farm. So this kind of treatment will pretty much always exist to one extent or another, especially in towns who do not fully respect any animals' rights.
