Uhhh, yeah. Only problem with your little make-believe scenario is that I could do a simple Google search and find no fewer than a dozen incidents involving Pit Bulls during a 30 DAY PERIOD in which people were bitten, maimed, killed, or otherwise injured in some way by these dogs. You could take one as a puppy and have it raised by a little old lady, and it may attack without warning or provocation. It has happened EXACTLY that way. That dog wasn't raised by gang bangers. These dogs are mentally unstable, and will always have a vicious, violent streak.
