What would it take to change your mind about whether pit bulls were safe?

There have been several pro or anti-pit bull questions, and many have stated their positions. What would it take to change yours?
Yesterday, in my town, 3 pit bulls killed a 2 year old that wandered into the garage. Do we still blame the owner? Can the breed be redeemed? How committed are you to your position?
