I suggest all airlines at the airport suspend advertising on the "journalists" station.
Regarding luggage, luggage handlers have been found to have keys to common cheap luggage locks (which are all the same). In addition, the hasps on those and some of the combination locks can be bent open and closed by hand, or using pliers.
Instead of standard locks I now use self-locking wiring ties, such as these . . .

Can be bought in the electric section of hardware stores. Slip one through where the lock would go and zip it tight. It cannot be easily removed without cutting (which I do with small nail clippers I keep in an outside luggage pocket).
