Getting back to the topic at hand:
The ALF is committing an act of hypocrisy - perhaps unwittingly. They are threatening and terrorizing a primate (the human researcher) in order to get him to stop harming primates.
I'm with Peter Singer on this one - I wonder if there is any actual ethical divide between all of us primates, and indeed most of the mammals.
Would I kill someone to stop them from inflicting fatal harm to a primate of a different species? Maybe, in the heat of the moment, I might.
But certainly this premeditated campaign of harassment and cruelty and punishment conducted by the ALF is unethical and indefensible.

BTW, I'd save the child, not the kitten - the question is moronic.
