I don't understand how PETA can be such heartless asses to people in a campaign to promote kindness to animals. Think of the woman's family and the family of her murderous husband - I'm sure that really helped them in their grief.
Here's something from PETA about it:
While people are rightly horrified at the thought of Hopkins' frozen wife, we're hoping that some good might come from pointing out that there's something wrong with stowing away any flesh. To highlight this, PETA has launched a new thought-provoking billboard, which we're attempting to run in Mobile, Alabama. We hope it makes some folks stop and think about how everyone—not just humans—is made of flesh, blood, bone, and emotions.
It makes me stop and think that PETA needs find its humanity and get some perspective. "Something wrong with stowing away any flesh" - WTH? This is brainless.
