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.

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.

The University of California has been selected as the poster child of animal abuse at laboratories. It's been shown that the tactics are more effective if you just hit one person over and over and get them to quit what they're doing.

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.

Violence has been a necessary component of every serious liberation struggle...Violence is not the only path to liberation, but likely an indispensable one...the Press Office would like to be clear on this matter: we support all the liberationists ­ from the graffiti artists and ALF liberator to the Animal Rights Militia, Justice Department and Revolutionary Cells.

If animal abusers aren't going to stop perpetrating these types of atrocities, they ought to be stopped using whatever means necessary. What we're starting to see is the implementation of that type of strategy.

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.
