And this differs from owning a pit bull how?
I guess it must be so, eh!
I guess that the white dog is just savouring a taste for later, eh?
Let me introduce you to Sergeant Stubby, a WW1 veteran, Pit Bull cross, who passed away in 1926. I guess you believe that he was 'not much different' from an alligator. You may be right, but I don't think the men of the 102 Regiment of the 26 Division would agree with you. Sgt. Stubby learned to warn members of his regiment, of poison gas attacks and incoming shells, giving them time to don their equipment and seek what shelter they could. He also located men in the no-mans land between the trenches, saving many GI's lives. But of course, he was not that much different than an alligator, right? Of course such a dangerous beast should not have 'endangered' soldiers' lives, in spite of however many lives he saved by warning of incoming shells! 
A pit bull, like any dog can be trained as they have a much more complex brain than an alligator. An alligator cannot be trained, other than to get food, even if it is the hand that feeds them. Are their many 'less than men' who train a Pit Bull to be vicious? Yes, likely to make up for, shall we say, 'short comings'!
Are there well-trained and well-behaved Pit Bulls? Of course! Of Michael Vick's 49 fighting dogs, one was euthanized for aggression and one was euthanized because of poor health. Twenty-five were fostered and 22 were sent to an animal sanctuary because of aggression toward other dogs, not people. Seven have Canine Good Citizen Certificates and three are therapy dogs in hospitals and children’s literacy programs. It is people like Vick that should spend years in similar accommodations as where they kept their dogs. Thugs that train a dog to make up for their 'short comings' should be the ones punished, not the dogs, a punishment that acts as an example to others, not to train your dog to be a killer. Unfortunately, few of these thugs know how to train a dog, merely teach it to be aggressive.
