Way more people get bitten by poodles/etc. than pits/Rotties etc.
The problem is that poodle/etc bites are generally not dramatic/lethal and don't make the news.
IMO ownership of large breeds whose bloodlines reflect protection instincts should require a higher level of legal ownership requirements (temperament tests, mandatory training level, insurance etc.).
Won't happen in goofyland in our lifetimes so its up to us to protect ourselves from these animals. I have a canine repellent sonic device I keep in the car (as well as a couple of more "serious" tools if needed) should the need ever arise to put one of these mutts down if it attacks me or anyone I care about.
