"Countless studies have proven that Pit-Bulls are a gentle breed and only bite when they are provoked…Did they ever find out what the 74 year old man did to provoke this gentle canine? I am sure that he did something to the dog or this never would have happened…"
Seriously??? The problem with pit bulls is the things that "provoke" them are things that usually won't provoke another dog to kill. Such as someone walking by, a dog being in the yard next door or down the block, dropping a pillow and picking it up, etc.
