Life imprisonment seems about right to me; hopefully he wont be out for a long time, if ever. I don't really care about Bridger, though. I care about myself; as in, I care about doing my best (inevitably failing, but still trying) to be a moral person in an immoral world. And two wrongs don't make a right.
I honestly believe that desiring and taking pleasure in the suffering of another human being, no matter how evil their acts, diminishes ME as a human being. Bridger may seem completely lacking in humanity but I believe that by supporting the killing and/or torture of another human being (because however much we might like to pretend otherwise, that, unfortunately is what he is) I lose my own humanity. That wont have any effect on Bridger, but it will certainly damage me. Sorry if this all sounds really pious, by the way; that's not my intention.)
None of us can do anything about Bridger and none of us can do anything to bring poor April back - but we can feel for and empathise with her family without demeaning ourselves by indulging in ugly and destructive talk. It won't have any effect on Bridger but it I guess what I'm saying is that I don't really see the purpose of this thread.
As an aside, I don't want to be rude, but I don't think that ad hominem attacks - ie calling people who don't support your view names, or labelling them (the "human rights" brigade, the "pc brigade" etc) instead of engaging with their points is very helpful. (Incidentally, as a Christian, I don't agree with "human rights" as such but I believe that as humans we have a responsibility to treat our fellow-humans with respect and that it's not up to us to decide whether they deserve it or not.)
