The Criminal Code contains numerous provisions dealing with animal cruelty but is silent on the practice of capturing and enslaving higher species of animals. Pictures of trainers in affectionate poses with naturally wild animals, such as the one in the above article, portray a  fundamentally distorted picture of the relationship between the parties. Rather than being loving friends as depicted they are really master and slave. How can we believe an animal with the intelligence of a child beginning to talk would love the people responsible for replacing its natural environment, comprising the vast breadth of the ocean, with a fish tank? Criminal lawyers and others with experience in sex crimes and domestic abuse cases often see photos of pedophiles and spousal abusers with their seemingly contented victims but this in no way diminishes the reality of their  actual victimization.

We only lock up criminals for major transgressions. What justifies doing it to magnificent, intelligent and innocent animals?
