About the liquor bottle . . . . . (spoilers)
Why didn't O'Toole wipe it down (to remove his fingerprints) right before setting it up on the pedestal?
Why didn't the Chief Guard demand that it be taken off the pedestal with white gloves and/or a clean cloth (to avoid contaminating it's surface with their own fingerprints, thus possibly obscuring the fingerprints of the criminal)?
I know . . . . movie logic.
