I hope Knut can be rehabilitated.
I know zoos don't have a lot of money - but I hope that some of the money that Knut brought in (it was considerable, according to one of the stories) will be used towards his care.
There is a scary pic of him snarling at a child (through glass, thank goodness).
Rehabilitation may be the only way to save his life.
