I mentioned aggression towards other dogs, yes, but also against people. The statistics cover attacks on people. They may not be 100% accurate, and probably don't take all questions into account, but it's undeniable that there's something there.
And it should be pointed out that even some good owners have dogs that attack. The Pit Bull that attacked my friend's husband and their dog last month was kept by what to all accounts seems to have been very responsible owners.
