Exotic Animals in the US

I completely agree with Kate Schlesinger about the officers shooting the exotic animals that were set loose in Ohio. I just watched the updated news on the problem and those officers actually killed 49 exotic animals; there were pictures and videos of the dead animals laid out in rows; execution style. In an article I read a man named Jack Hanna said the officers couldn't’t tranquilize the animals because it was impossible for these exotic animals to be tranquilized. He also said that the fact that it was dark at the time, the animals would have been “drowsy” from the tranquilizer and ran off into the other neighborhoods and hid until they woke up. I also agree that there should be a law against people owning exotic animals. When Hanna was asked why was the man allowed to own these animals with his pass record Jack Hanna said that after this incident people will have to meet certain criteria’s to own exotic animals, but only in Ohio. The only states in the country that completely ban the owning of an exotic animal as pets are: Alaska, California, Colorado, DC, Georgia, Hawaii, Illinois, Iowa, Kentucky, Maryland, Massachusetts, New Hampshire, New Jersey, New York, New Mexico, Oregon, Vermont, & Washington.
But I want to go further and say that I honestly do not see a need for exotic animals in the U.S period. I understand that America has countless Zoos and I understand that the incident in Ohio had nothing to do with Zoos, but what exactly is the purpose of having these wild/exotic animals caged in "our" world? I don't see a need for it at all; in zoos or for personal entertainment. The animals aren't in their natural habitat nor are they living the lives that they lived before they were caged by humans. they live around artificial settings that give the animals the illusion that they are "home", but I believe that these animals are too smart to believe that a zoo is their home.
I believe that a tiger in a zoo wakes up every morning feeling like a tiger, but the tiger cant do the things a tiger in the wild would do. The tiger has to "entertain" the thousands and thousands of people who walk pass the glass, stare, and take pictures. The tiger in the zoo cant move beyond where he is at and for what reason? So some kids and "animal lovers" can witness the tiger living its fake life? What pleasure does the tiger get from living in this zoo?
