The bill makes special exemptions for people who make a living off of fondling animals: veterinarians, those who dabble in animal husbandry, and livestock judges. However the language of the bill may be particular troubling to those people who believe in evolution, as it effectively bans human sex with any animal; this would seem to include Homo Sapiens.
This was the state's third attempt to ban bestiality. Previous legislatures didn't support the practice. They just didn't think enacting a law warranted their time.
This was before a slew of sex crimes with various barnyard animals rocked the state, or at least provided interesting blurbs for News of the Weird. The issue gained national attention a few years ago when a Florida man accidentally asphyxiated Meg the goat while having sex with her. The police could not link the man to the scene of the crime, but he was arrested a few months later in a separate goat abduction case.
It would seem that the majority of these crimes could be punishable with animal cruelty laws, or in the case of goat abduction, property laws. However these laws would become ineffective if an animal lover owned the object of his affection, and if the owner could convince a judge that such acts weren't cruel. The question nobody wants to ask is, what if the animal enjoys the interspecies sex?
Perhaps a better moral stance to take on the issue is that this law may help prevent the spread of disease. Most diseases are species specific, but there are enough that can be transferred between species to cause concern.
In the end this legislation will do very little to discourage bestiality. It's not as though zoophiles are open about their lifestyle. Researches estimate that between 2 and 5 percent of the population harbor sexual desires for animals, and yet not a single one of the estimated 600,000 zoophiles in Florida came out to protest the law. The public shame of being caught with an animal is a far worse punishment than a misdemeanor charge.
