Wet paper bag or industrial safe?

A quick post this time (I promise!)

Pop Quiz, hotshot. What's more secure:

(i) a wet paper bag holding a couple of stale tic-tacs (site requires Flash); or

(ii) an industrial-strength safe holding $1M in diamonds?

Is security a property of the object itself (wet paper versus thick steel), or of people's disposition towards it (indifference versus greedy desire)?
