Is this a real question? If it is, a target that you are shooting an arrow at is an inanimate object. It's still a target.
But to clarify, if a residence or place or something that people might be present at is a target, it means that ANYONE could have been there and that person would have been killed.
Shooter with the Zoo as a target. Doesn't care WHO gets killed as long as they kill someone. The Zoo is the target, not the people. Maybe the shooter hates the zoo so he wants all people to be afraid of the zoo. Does that help?
