I think there's a morality line here that @sandworm101 kind of misses.
I'm pretty okay with eating domesticated animals. I was sad that I couldn't find horsemeat when I was in montreal. If dogs are raised for the slaughter, I'm okay with that.
What Nguyen Dinh Phong was doing was totally different. He was abducting people's _family members_ in the night, and killing them in a callous way.
That's why he got lynched, that's why he is more evil than that dog-restaurant he sold the dogs to.
