Stand your ground and still die.

A canine cop and dog were trailing a suspect in pine woods in southwest Florida. The dog stuck his/her face into a rattle snake and got bitten. Here is the part that pisses me off. The cop shot the snake and then took the dog to a vet for anti-venom. The dog survived and the snake did not. 
Now remember that Florida is a "Stand your Ground" state. If threatened you may use lethal force to defend yourself. You are legally entitled to kill the threatening person. So the snake was in its own territory, minding its own business when threatened by a dog. The dog didn't back off, so the snake stood its ground and used possibly lethal force in defending itself. For this it got killed. And the cop who pulled the trigger? No charges. Murder of an innocent. 
Ok, I realize that the laws of people usually don't apply to animals. Usually but not always. Say a pit bull bites a person in an unprovoked attack. The dog will be captured, quarantined and possibly put down. Not shot on the spot. 
Ok, I realize that snakes aren’t pit bulls. But they are just animals trying to survive in an increasingly diminishing landscape. They are NOT the aggressor. We are. They do not deserve to be killed just because they are snakes, or because they defended themselves. 
So what should the cop have done? Pulled back the dog and gone to the vet for a shot. Not killed an innocent animal that was merely defending itself in an unprovoked attack. Merely Standing its Ground. Maybe if the snake was named George it would have survived.
