Below is a good video put together that highlights much of the testimoy in South Dakota and Utah for the passing of their statewide bills that preempt municipalities from passing laws targeting specific breeds of dogs.
The testimony tackles property rights issues and the state as a check of abusive local government policy. It tackles the issue of personal responsibility and accountability. And it tackles the issue of inconsistent laws that create scenarios where a person can be walking down the street with their dog and by the very nature of crossing the street and into another juristiction can then be subjected to criminal charges for simply walking their dog which is not legal on the other side of the street in the neighboring juristictions.
"Law and policy should be based on individual actions and individual merits, not on classes "- Representative Nielson, Utah.
Preemption laws have been passed in 18 states in the US. Learn more in the 8 minute video:
