You could have switched the "safe" liquids for some "evil" liquids that were in your checked luggage before rechecking your bags, and hence be carrying "evil" liquids onto the plane.
IF (and I'm not supporting this if), you believe that having a liter bottle of unknown liquid in carryon luggage on a commercial airliner is enough of a security risk that it should be barred, then the policy goalie describes above actually makes sense.
if done correctly, all duty free liquids would have a tamper proof security seal on them. i find it "rather quite diffcult" to un-cork/open a bottle of wine/cognac/scotch/etc and re-seal it (including "tapping the bottom" of the bottle without proper tools as the bottle would break) with all the appropriate items such as a properly inserted cork, foil wrapper and the aforementioned (tho hypothetical) security seal.
another issue along the same line...i was given a bottle of wine by the purser on a domestic ua flight but my problem was that it was on my outbound flight and if i brought it back home with me on my return flight, i'd have to check it. remember, this is an alledgedly secure bottle as it was airline property before it was given to me. again, another reason for a tamper resistant security seal of some sort on bottles.
n.b.: upon arrival at my friend's house, his wife and i thoroughly enjoyed the wine ^ but again, the logic defies me
