No one who knows the breed doubts they are the number one most capable of misdirected harm when in the wrong hands. The problem is that they've been in the most possible wrong hands since they came to be celebrated within the "gangsta" hip hop culture back in the late 1970s. Within that community, their numbers have been wildly high since that time, and they've been encouraged by these folks to be human-aggressive by long-known methods. Prior to that, however, they didn't even make most lists of dogs that bite. Look at a World Almanac from the 1960s, which always maintained such a list, and they don't even make the top ten. I believe it was German Shepherds that topped the list at that time.
