Yes, this is horrible but I think it’s either a Halal or Kosher operation (religious exemption). I’ve been to a number of beef slaughter plants for my job and that’s not how it’s normally done. The cow is rendered unconscious by a captive bolt gun and then bled out.
There is roughly about 2 billion Muslims on the planet, so I'm thinking this is one example of many where humans routinely torture and kill others on a mass scale
