Some of the animal activist would see the loss of the animals as a way to make a point, their point would be that if they were not kept like they were, then this would never have happened, the animals would be just collateral damage. Kinda like the people who go to labs and such and just turn chimps and other animals loose, without the thought of how they will survive, is it right they are being used for testing? no it isn't, but is it right to turn them loose into a environment that they have no idea of how to survive?
