Unfortunately, "commonsense" arrangements aren't being made, or we wouldn't have this discussion, right?
Pit bulls are dangerous. Any ban would remove the danger of attack.
Any "accountability" on the other hand is only applied after the fact.
There's all kinds of things, when not used with common sense get people injured or killed. Like firearms. If we just ban firearms then we remove the danger of somebody getting killed. Accountablility for a criminal shooting an innocent person is only applied after the fact.
