AIBU to think that's the least of it?
I can't stop thinking about it, it's so horrific. The poor families and neighbours and everyone involved or touched by this. Hearing it said that its somehow Amazon's fault sounds completely absurd to me. He produced ricin for goodness sake, if he didn't get the knife from Amazon it would have been somewhere else. This incident should (and will I believe) change history. And it has NOTHING to do with where or how he got hold of a knife.
