Must a Sentry Gun attack target the player or NPC whose turn it interrupts?

Question

Accepted Answer

Unclear. The card does not restrict the target, and early replies read it as unrestricted. A later post argues the spirit of the card is to shoot the player or NPC whose turn you interrupt, and the compiled thread shows Ira Fay agreeing with that analysis, but there is no published ruling.
