Feel secure?

By now you’ve probably read about the investigation that showed just how lax security can be at federal buildings. (Read about it here.)
Undercover officials from the Government Accountability Office successfully smuggled bomb-making equipment 10 times through checkpoints. They then assembled the bombs and walked freely through places housing agencies such as Homeland Security, the State Department and the Justice Department.
This wasn’t the first time investigators have been able to sneak by security guards with deadly items. My guess is it won’t be the last, either.
Five years ago, Canadian officials found their airports so lax that official badges and uniforms wound up on eBay.
A clue to this problem may lie in this story. Every week, 1,200 people simply leave their laptop computers at security checkpoints at Los Angeles International Airport, or they have them stolen.

We’re all human, which means we have limited attention spans. That includes security guards charged with the monotonous task of checking thousands of people each day. It’s not an excuse, but it is a fact.
My question is, do you feel secure when you fly, knowing everyone has passed through security? How about when you enter a federal building?
I’ll bet you were fairly secure right after 9/11, when everyone was on guard. But I honestly don’t know how you keep up that level of vigilance day after day, eight years later.
