The bottom line is the pit bull community needs to find a way to police itself, otherwise it will be done for them.
"Pit bull community" is a pretty nebulous term. You could also say "Gun owners need to find a way to police themselves." If you've ever been to a well-run range, you'll know that the overwhelming majority of gun owners (in my experience and associations) are very responsible, conscientous people. That doesn't stop daily shootings or news accounts thereof. I spend far more time (basically daily) at a local dog park than I do at the range, and could log daily stories of pit bulls playing with other breeds without incident, but that would be purely anecdotal as are these news stories, and should be given similar weight in the debate. Essentially, irresponsible people who care little about the well-being of their dogs seldom bring them to the park to socialize them with people and other dogs. To ban the breed altogether would set a very, very bad precedent, and play right into the hands of PETA and any other number of *animal rights* groups.
Frankly, I'm glad to see pit and other dog owners starting to be held to account more often, and I suspect this will curb some of these admittedly horrific incidents.
