Thanks for the post. I can't watch the video because my computer is S-L-O-W, but I hope it can open someone's eyes.
When I was in highschool I volunteered at the city animal shelter (read pound), and at that time there was a city ordinance against the adoption of pitbulls. Most all of the animal control techs hated it. Even at the counter if someone brought in a pitbull, they'd let them know that the dog would inevitably be euthenised unless they took it out of the city to the SPCA. (Which is really still in Sacramento, just city lines haven't been updated in ages.) If they could they'd always put boxer/terrier cross, or anything similar that they could get away with. The reason?
Yes, pit bulls are potentially violent dogs. Infact, most of the dogs they had in quarentine were pitbulls. And if you asked any of the ACTs about it, they'd tell you the truth. Most all (about 90%) of the pitbulls were there for attacking...... other animals.
What about other dogs? (the ones that made it into quarentine.)
They told me that easily half of all Sharpeis, Chows, Rotts, Akitas, and ???? (there was another one but I can't remember it) were in quarentine for attacking a human. With a couple of these breeds they'd tell you that they were most commonly family members even.
Funny how pitbulls went from being one of the most popular family dogs in the 30's (because of the lil rascal's Petey) to one of the most feared today.
That being said, Pitbulls are not for everybody. They are very highstrung and determined. This can make them very distructive without propper attention. They can be dangerous to your other animals, this is more likely to happen if you have more than one. (The more than one rule pretty much goes for any med-large breed dog. My cousin's pair of rotts have killed 4 cats so far. Why they keep replacing them is beyond me

) We've had one, he was very lovable and sweet. He never chased our cats, but we had him from a puppy. He was distructive though, and not well suited for an apartment. He took out the front window one day climbing behind the speaker to sneak out the door. My mother's friend has had many. He did have one bad seed, but he kept her and prevented problems from happening. (kenneled her when people came over or when he was not home, under lock and key even. ) She was a great dog. He'd give her commands from outside the kennel and she'd listen. He just wouldn't let her out when we were there, because she very commonly perceived people ready to harm him. The one he had before her, Pappy, had terrible arthritis. He was such a lover and so eager to please. He could hardly walk but to his last days he'd still dive four feet down in the river to pull up the EXACT rock you threw in.

He was the greatest dog.
