LOL, I know, it is an international conspiracy about phantoms.
As for your dog bite studies, read the studies' sources carefully. Most get their data from police or media reports. Neither police nor the media are experts on dog breeds any more than the media is an expert on firearms.
That's why, instead of identifying an American Pit Bull Terrier, or an American Staffordshire Terrier, or an American Bully, or a Bullmastiff/Labrador mix, they say 'pit bull.'
My money's on American Pit Bull Terriers being the vast majority of the problem.
