I read the local newspaper today and I stumbled upon a sad article about something that had happened recently to someone in my community. Here's the story: Someone was walking his dog in the park, someone else walked his ferret in the park. The dog killed the ferret. The dog owner isn't charged with any crime.
Why? The police said "This isn't a crime as a ferret isn't a person, it's a thing." This really upset me. For one thing, anything you say about others applies to yourself as well, so saying "they aren't people because they're not like me", equals "I'm not a person because I'm not like them". If you say someone isn't a person, don't make excuses when you get the same accusation.
The second thing is that, although you cannot keep animals in the wild from killing each other, animals that live with humans, in a way, are human. They are not wild animals in the forest, they are our beloved, protected family members that we try our best to keep safe.
Also, we have the responsibility that our animals don't hurt anyone. So, if by your negligence, your dog causes harm, you are the one guilty of a crime. In conclusion, if, by your negligence, a dog that you keep as company, kills a ferret that someone keeps as company, you are responsible for a death.
Besides, even if your dog only ruined a "thing", as opposed to killing a person, it would still be a crime. Destruction of property, you know.
