Just how dangerous are pit bulls?

I don't have a dog right now but I'd like to get one someday. I really like Boston Terriers alot. I couldn't bring myself to own a pit bull because of the facts here. They don't have a high biting rate, but when they do they have a higher fatality rate than other dogs. That says DON'T piss them off. Ever. The American Temperament Testing Society evaluated 122 dog breeds and found that the American Staffordshire Terrier, a type of pit bull banned in Denver, passed 83.3 percent of the time, just behind the golden retriever (83.6 percent). The American Canine Foundation calculated rates of human dog-bite fatalities by breed and found that pit bulls bite at a lower rate than many other dogs. The Doberman pinscher was found to bite 10 times as often as a pit bull. Still, pit bulls and Rottweilers have caused the most deaths, according to a study by the Centers for Disease Control and Prevention, the American Veterinary Medical Association and the Humane Society of the United States, which examined 20 years of dog-bite data. That same study concluded fatal attacks "represent a small proportion of dog bite injuries to humans, and therefore, should not be the primary factor driving public policy concerning dangerous dogs." Julie Gilchrist, a CDC doctor who researches dog bites, said many factors go into biting risk, including the health of the dog and how the animal was raised.
