Who’s really responsible for this crazy Airbnb theft?

Did Renata Lambert steal a TV from her rental apartment in Warsaw, Poland? Lambert says she didn’t, but her host insists she did. Now the two parties are locked in a dispute over an Airbnb theft that she thinks I can settle.

Lambert’s case raises questions that have no easy answer. How do you prove a guest took something from your rental? If you’re a guest, how do you prove it wasn’t you? And what’s Airbnb’s role in mediating these conflicts?
