Who is calling for a realistic and minimalist permit system? I see groups trying to ban all exotic pets, including reptiles, and they are having success at the local, state, and federal levels. This isn't some tinfoil hat conspiracy theory... this is real and it is happening. They will smile, shake your hand on a minimalist system, and then will push for more the second it's in place.
I may be mistaken but wasn't one of the prime reasons for the Myrtle Beach show starting because FL was going to make it impossible to have hots at Daytona? I may be wrong on that but it's what I recall through the grapevine years ago. Regardless, FL isn't exactly the poster child for exotic animal friendly policies.
I have the perfect way to differentiate between responsible owners and the people who are doing it wrong. It won't take any additional regulations and will have a profound effect on those who are behaving irresponsibly. It's called charging such people with public endangerment, involuntary homicide, assault, etc. when such an action is called for. It's the exact same system used for dog and livestock owners who are held accountable if their animals cause injury or death. Prison and/or loss of your house depending on the level of negligence will differentiate between owners real quick.
I don't have the numbers but I'm quite sure a significantly greater number of people are killed or injured by just pitbulls than by all captive exotics combined every year in America... do we need a nationwide permit system for pitbull ownership or is it enough to hold irresponsible pitbull owners accountable when injuries occur?
