If (a particular researcher) won't stop when you ask nicely, when you picket in front of his house, or when you burn his car, maybe he'll stop when you hit him over the head with a two-by-four.

This is historically what happens whenever revolutionaries begin to take the oppression and suffering of their fellow beings seriously, whether human or nonhuman. It's regrettable that certain scientists are willing to put their families at risk by choosing to do wasteful animal experiments in this day and age.

I'm not saying people should go out and start killing," the California-based Vlasak says. But he's not saying activists shouldn't kill either, even though he's a doctor, devoted to mending people. "There's a lot of violence used against animals" Vlasak rationalizes. And some of those responsible won't stop, he says, "until they are forced to stop.

Nothing is more violent and radical than what's being done to non-human animals in our society. If a researcher won't stop abusing animals and is stopped physically, whether with the use of force, or is killed, I certainly wouldn't lose sleep over that idea.

If that means going onto their farms, releasing their animals and burning the place to the ground, that's morally justifiable, in our opinion...There were always innocent people who got hurt somewhere along the way but it was important that those who oppressed one group of people be stopped, and we don't see the animal liberation struggle being substantially different from these other struggles.... A sustained campaign against a particular industry or a particular organization has the potential to be quite effective.

I think violence is part of the struggle against oppression. If something bad happens to these people [animal researchers], it will discourage others. It is inevitable that violence will be used in the struggle and that it will be effective.

As far as the underground liberation movement, it won't have any impact at all because they don't really care about those laws. Their activities - sabotaging, liberating animals - are already illegal so just adding one more law won't make much difference.
