I don't think eradicating is the way to go but there should definately be harsher penalties for people who are irresponsible owners. They can be a dangerous dog and anyone who buys one should know what they are getting themselves into. You hear so many stories about how a pitbull escaped and attacked someone. If the owners were responsible enough and kept them locked up when they're not around and under supervison when they are then there would be no problem. They should also limit the amount of pitbulls someone can own because they are often kept in "packs" of 3-4 which leads to an aggressive nature as they often fight with one another.
