I think Dario Ringach is a poster boy for the concept that the use of force or the threat of force is an effective means to stop people who abuse animals," "No strictly peaceful movement has succeeded in liberation," "I think the animal rights movement has been restrained in its use of force, mostly because people in the struggle are often people of privilege who aren't willing to risk losing that privilege.

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.

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.

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.

Things are picking up...It's not going to make this thing go away... don't think you're going to find anybody deterred...There's a lot of people willing to die for the cause.

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.

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.
