The main animal activist that seems to be quoted in most stories about Knut has complained about the context of his original claim being ignored. Previous to Knut's birth, there was another zoo that had a different kind of bear cub rejected by its mother and the zoo decided to put it down. The activist, Frank Albrecht, sued the other zoo to prevent them from putting down the bear, but his case was just tossed out as it was deemed humans raising a rejected cub was unnatural. So when Knut was saved, he complained that if the previous cases had any proper legal standing and the law was consistent, the people in the previous case should demand that Knut be put down for the same reasons they did with the other bear. Since Knut had quite a bit of popular support, it was not expected anyone would legally challenge Knut's rescue, but instead serve the purpose of highlighting the problem of there being zoos that do the opposite of what was done with Knut.
