I'll be checking replays in my inbox tomorrow. Second place prize is still open!
And you're right, the standard issue towers would kill the inspector. I never even tested those towers killing the inspector on the hardest difficulty (his life scales on difficulty, even though he dies in one hit). But even if those towers didn't kill him, he'd leak and you'd get the same dialog as if you intentionally murdered him. If you know how to break the game to that extent (probably impossible) then you probably also know the story!
