Actually, no they are not.  The American Temperament Test Society, Inc. (ATTS) breed statistics as of December 2005 show an 83.5% passing rate for the American Pit Bull Terrier and the American Staffordshire Terrier and an 84.7% passing rate for the Staffordshire bull terrier, as compared to an 81.2% average pass rate for all dog breeds. That's better than the popular Border Collie (a breed who scores 79.6%). What would you rather be attacked by, a Pit Bull or a Border Collie? :rofl    I will never, ever understand this pit bull revisionism.
