[Gumshoe seems to actually mull that over a bit. Wheels turning, chin scratching, that sort of thing.]

You know, I never really thought about it like that, but that does make sense. I mean, the only time I've ever been to places like this was for work, and that usually means something pretty bad went down. But before that happens, it's pretty clear cut how or why they got there to begin with. Still, I'd be neglecting my job in a situation like that if I just assumed and didn't make sure to ask any witnesses or people around at the time.
