Logic dictates that a gun is dangerous, therefore you need a permit. This helps keep a dangerous item out of the hands of the irresponsible. The same logic applies to large predacious animal ownership. You want to own something that has the potential to infringe on your own safety as well as others you need a permit. Its legal for anyone to buy a carnivore that is capable of swallowing a child and can overpower multiple people. That is scary.
