Furthermore, it is a fact that this type of behavior often leads to evem more grizzly behavior, involving people. This person needs to be tried, convicted, and watched very carefully for the remainder of his life.
I have heard this argument, yet I have never seen one documented study or a single fact to back it up. When the guy kills a person call the police. Otherwise, it was just a few ducks (animals-not people). The only reason that it should even be investigated is that apparently according to another post, the ducks were the private property of the car wash owner. So prosecute for destruction of private property-only.
