At least in the US, Law is really defined by court precedents, not by some stupid wording.
This is a good thing. Imagine a "Don't murder anyone" law. Without a court to decide what that actually means, I could argue that if I put a timer on a bomb, I didn't murder anyone - the bomb did the killing, and I didn't even trigger it directly. How is a bullet any different except that the delay is shorter? Dumbass didn't get out of the way, I say. No different than someone standing in the middle of a highway. The english language isn't like a programming language - its remarkably open to interpretation as to meaning, hence the need for courts to define what the law means through actual examples.
