This has been an ongoing issue with circuses that use animals to perform since as long as there have been circuses. I urge anyone who comes across this to visit the link and see how those animals are treated just so a few idiot humans can get their jollies.
My personal take is I agree with many, should one of these trainers ever cross my path I don't believe that I'd take the nobler higher road. Nope, it's ass kicking time.
For a compare and contrast Elephant Art or AEACP
