Hee hee, good observation. The reason for this is because the word "Not" is a logical negation ... and there are actually supposed to be other choices that aren't yet coded:
- Has
- Not Has
- Had
- Not Had
- Has/Had
- Never Had
Do those make sense? So the idea is, if the user picked up the gun and used it up ("Had"), then you could write about that. Otherwise, if he still has it ("Has") ...
But I agree, this is confusing, and possibly ([probably) overkill.
