So was there DNA evidence found on those handcuffs and leg irons? That would actually be "damning" evidence. I don't mean to alarm you, but there are some people who actually do use those things, ropes, gags, and a lot of other items for consensual sex. Possession of those do not indicate a crime has been committed.

PT was not a demo. It was a playable teaser for another game. You might be focusing on "teaser" but don't ignore the "playable" that indicated that this was indeed a game.
