Wary of secret service agents, nosey journalists and even greedy gamblers spying on the conclave's deliberations, the Vatican has hired espionage experts to inspect the Sistine Chapel for hidden microphones and spy cameras.
Got to follow the money on this one. The gambler could make some money (what are the odds in Vegas on Papal election, BTW? ), the media outlet with the "ins" on the story would selling millions/billions of dollars of advertising and papers/magazines. Secret service wants to know, so they can start the snooping into the background, and expectations of leadership style, etc, etc. Probably hasn't happened too often before in Papal elections, but I thinks it a good idea.
