I agree with you, we do have too many laws. However, I see nothing wrong with writing a law protecting innocent people from being mauled to death while they should be sleeping peacefully in the beds at night. I’m getting tired of these mauling stories. Pit Bulls are bred to be mean and even when they look sweet and cudly that mean side can come out without any warning. Ask the family whose baby was killed by the sweet family pet. If nice people are having trouble with pit-bulls, then what about the gang bangers who train them to be mean? That’s a big part of the problem right there. I don’t know where you live, but in my part of the country, gang bangers and pit bulls are a problem and I don’t even live in a big city.
This whole phenom of folks acquiring 'bad' dogs is the result of an emasculated populace where 'the state' has decided what you can and cannot do ie. self-defense which leaves you limited options, one of which is to acquire a pit bull (rather than carry a loaded gun and do 5-10 for possession)
As a contractor, I'm required to maintain a million dollar liability insurance policy (up to 3 million per occurance) should someone be harmed by my work. I see no reason at all to exempt pit owners (and any dog with pit blood) from such an insurance requirement. Let the risks associated with this breed be allocated to the owners according to the costs the market will determine. For a couple of hundred bucks a month, they can enjoy the 'companionship' of their pit, while mauling victims will have access to funds needed for reconstructive surgery, pain and suffering, trauma, etc.
Then pass a local law for your local area by your local politicians and keep the feds out of it.
