It says they bought this dog online, so they couldn't possibly know the dogs history. So many dogs sold online are stolen, overly aggressive or banned breeds....What were they thinking
As for the man who was killed, that's tragic. Its unbearable to imagine what he must of gone through. Too many gangs are now using bully types as weapons of fear. It does need to be sorted out, but lets remember, most vicious dogs are an extension of their owner.
