Somehow it is OK for a wild animal to stalk, pursue, capture an
eat another critter yet let a human simply grab one and it is somehow declared some giant sin against nature. All those "harassed wildlife" from the video got a valuable risk aversion lesson with no visible bites or damage and quite possibly may live longer lives as a result. They shall live to run away another day. While I do not necessarily recommend wrestling wild boars to teach them how to escape a panther I do imagine the boar preferred it to being shot or chewed to death by either man or beast. And how much kinder it was to those animals to be released rather than caged and sold into some sort of zoo-like slavery.
If you are upset by apparent cruelty or illegality in your jurisdiction perhaps you could lobby to also ban animals from eating each other, rodeos, slaughter houses, sport fishing ( especially that heinous catch-and-release barbarism), vegetable harvests without anesthesia, long winded political speeches and other unpleasantries. Or join me for my spring bear-baiting festival where we drag them out of their dens, dress them up in silly hats and post their pictures on Facebook before tucking them back into bed.

Just kidding, but I enjoy pointing out the irony of unregulated natural behavior vs, legislated civilized behavior.
