I was rooting around in my bag a couple of hours ago looking for a nice pen I “borrowed” from the Mandarin Oriental in Geneva (very nice hotel — pushing US public policy in a more pro-Rolex direction is now my top priority) what did I find but a Swiss Army Knife that someone or other had put in one of my Switzerland gift bags. I didn’t really think much of it, but on reflection I carried the bag in question onto the plane for the Geneva-JFK leg of my return travel. And I cleared security for the JFK-DCA leg with the knife in the bag and only didn’t wind up boarding the flight because it got canceled.
In the latter instance, I was even singled out for special enhanced scrutiny, but they still let me take a knife on the plane — the precise thing all this security is supposed to prevent. But God forbid I’d tried to walk through security with a couple of brought-from-home Diet Cokes to drink while waiting — there are big markups and profits at stake in the liquids ban.
