Security maven Bruce Schneier tackles the elephant in the room where post-9/11 security is concerned. Worth your time.

He opens with what is essentially a distillation of his position. He’s on solid ground here:

Since 9/11, we’ve spent hundreds of billions of dollars defending ourselves from terrorist attacks. Stories about the ineffectiveness of many of these security measures are common, but less so are discussions of why they are so ineffective. In short: much of our country’s counterterrorism security spending is not designed to protect us from the terrorists, but instead to protect our public officials from criticism when another attack occurs.
