That's not accurate, and is most likely highly edited footage. Shearing a sheep is not only harmless to them, but actually helpful. If a sheep's wool gets too long, then it can't move around properly and will die.
@Streetwise It's not normal practice and will most likely be met with criminal charges in most countries, if not jail time.
A sheep being shorn is basically the same as a human getting a haircut. Literally the only animal rights organization who says otherwise is PETA, and they kill animals and are a corporation in disguise.
