"A billboard for McDonalds was graffitied with animal liberation
slogans. The billboard was altered to read simply 'Be Prepared.'

We have seen behind the walls that allow the veneer of decency
towards animals to continue unquestioned. We challenge everyone
to go to a factory farm, a slaughterhouse, or a vivsection lab
and see for themselves what horrors are behind those walls. After
you have seen the suffering first hand, we have no doubt you will
join us in the fight for animal liberation."
