For one day the German news were full of this story, and most reports were far too hysterical on the subject. I think Walli and Frank can second that.
I've flewn a lot of times from Munich airport to other countries, and security in Munich isn't executed in any other way than on other airports. In fact, Munich is considered to be one of Europe's best organized and most modern airports. But that doesn't mean a human being who works as a security guard can't make a mistake for once. Of course it shouldn't ever happen, especially if you have such a responsible job, but we are all human and make mistakes. A German politcian said something about this being a human failure and not a technical or organisational problem, and he suggested using more personnel to avoid such incidents in the future. In my opinion this was the only reaction that wasn't completely inappropriate. I bet the guy who made the mistake feels really bad anyway, he doesn't need to be punished additionally.
And about your strange point of view...I second that as well. Maybe you should look beyond the borders of your own country - wherever you may live - and stop being so disrespectful about other nationalities and people who suffer from nature's catastrophes such as the victims of Haiti. If anything's disgusting, it's your coldness and missing sympathy.
One final note, just for the record: I've been to the USA for five times now, and seldom I've met so many friendly and heartwarming people. Other nations can learn a lot from America in terms of friendlyness and service.
