The neighbor's dog kills your daughter. And the redneck owner says, "That chain is plenty strong as long as kids don't get him mad."
And you walk away and drop the whole thing?
I don't think so.
I'm not talking about redneck owners or little girls. My example used the same circumstances. Three drunk guys torturing a dog with sling shots from across a fence which has always contained a dog before. If you'd place all the responsibility on the owner, you don't believe in the concept of personal responsibility at all.
As I said. The zoo gets 50% of the blame because the tiger could get out (even though it never had before) and because it's a public facility that should do what it can to protect its visitors. The men get 50% of the blame because their attack on the animal drove it out by deliberately hurting and enraging it.
