In Florida, the inspector is on the look-out to see if the bees in a hive have been Africanized, and can demand re-queening or other corrective measures if the bees show signs of it.
That won't stop the spread of the African bee, but it can prevent other problems. And I don't think that liability insurance (either on a apiary business or private home with a few hives) will pay damages if a person was keeping bees in violation of the law and someone gets hurt. Beeks in the city or suburbs need to be mindful that most people have zero understanding of bees, while many have an irrational fear of bees. If people know that you keep bees, they might blame you for any and all stings they get, even when they are the fool to blame, even when it was not a bee that stung them. Being able to show that your hives were inspected each year and that you were mindful of the law is important for urban/suburban beeks and for those who engage in beekeeping as a business - like it or not, the bar is higher for people in those groups.
