Other dogs are commonly known to attack children, people and dogs. There are many humans who attack children, people and animals. Blame all for the comparative few? I've known several pit bulls who are full of love, well-trained and under the control of their owners. Swimming pools are known to be very dangerous when not properly guarded. Shall we get rid of them, too? Animals don't deserve to be killed if they've not shown themselves to be harmful or aggressive. Not all pit bulls are aggressive.
