The lead investigator in the Andrew Oberle case (the grad student attacked by chimps on Thursday) has ruled that the chimps will not be put down for the attack. Their violence was excusable as defending their territory and Oberle, a trained researcher, should have known better than to approach so closely. 
I think this is the right decision, and an important one. We can’t vilify animals every time a human makes a mistake, and when they are doing what is natural and expected of them the punishment should not be death.
