Wine as a weapon?

We have just travelled back from a very successful tasting in Ireland, carrying a few gifts in our bags as we passed through the airport. Amongst our hand luggage we had some pieces of glassware, and this action served to rekindled a thought that I had a long time ago concerning airport security.

No doubt we have all heard many a tale of wine producers (and others) losing their corkscrews to over-zealous security guards. Nail files, pen knives, nail scissors and the like, no matter how small, have also fallen victim to the ever tightening restrictions. On our flight today one poor Expat returning to the USA even had his precious Heinz salad cream and HP Sauce confiscated as it was somehow deemed a threat. I know from experience as I once lost two jars of peanut butter in exactly the same way!

I'm sure that you have already guessed where I'm going with this..... I find it incomprehensible that passengers can still shop for glass bottles in duty free and then happily carry them on to the aircraft. Surely a broken bottle would constitute more of a serious threat to the cabin crew than some poor winemaker's corkscrew?
