You know driving is dangerous, but you still drive a car.
Getting killed by a terrorist is not in the top 10. Not in the top 1000 causes of death.

Why are we spending so much money and effort to stop the odd goofball trying to light his genitals on fire?
In 2002 the TSA had 13 employees. Today, 60,000 employees. Do you feel safer?
TSA and Homeland Security spending is obcenely wasteful.
From an excellent opinion piece by DAVID BROOKS:
… In a mature nation, President Obama could go on TV and say, “Listen, we’re doing the best we can, but some terrorists are bound to get through.” But this is apparently a country that must be spoken to in childish ways. The original line out of the White House was that the system worked. Don’t worry, little Johnny.
When that didn’t work the official line went to the other extreme. “I consider that totally unacceptable,” Obama said. I’m really mad, Johnny. But don’t worry, I’ll make it all better.
Meanwhile, the Transportation Security Administration has to be seen doing something, so it added another layer to its stage play, “Security Theater” — more baggage regulations, more in-flight restrictions.
At some point, it’s worth pointing out that it wasn’t the centralized system that stopped terrorism in this instance. As with the shoe bomber, as with the plane that went down in Shanksville, Pa., it was decentralized citizen action. The plot was foiled by nonexpert civilians who had the advantage of the concrete information right in front of them — and the spirit to take the initiative. …
Body scanners wouldn’t have caught Northwest bomber. Airport pat-downs are an exercise in futility.
How long before we in North America finally adopt Israeli security?
… Immediately after the first bomb goes off in the entrance of the airport. Before you take your shoes off.

Great posts, both this one and the one about Israeli airports safety.
But I can already see the money being wasted in high-tech-fancy-equipment.
