Disturbing Hallowe'en Decorations

A house in our neighborhood is decked out with the most disturbing Halloween decorations I've ever seen. The theme: an insane asylum, possibly haunted.  Particularly troubling are the bedsheets stretched across the windows... from the inside. Scrawled upon them are the words "Danger -- Keep Out" and "Help" in ghastly red letters.

Something's not right. Apart from the obvious -- someone may be in danger -- those messages conflict with one another. If a person is being held in that house against their will, why would they create a sign that says "Keep Out" right next to the cry for help?

This has gone too far. Perhaps I should call the police. Or better yet, launch my own covert rescue operation....make a citizen's arrest, if necessary...tonight.
