Bull Terriers are not even close to being the most populous breeds like Golden Retrievers, Labrador Retrievers, German Shepherds, or even chihuahua.
Bull Terriers and Bull Terrier mixes are responsible for 2 out of every 3 people mauled to death by a dog. So they have killed double the number of people as all other dogs combined. That is not “a few bad apples”, that is a breed characteristic.
The numbers of Bull Terriers that snap and maul someone to death are relatively small. It is not a common ocurrence, but the fact is that Bull Terriers are the deadliest breed by a wide marging.
