Former Transportation Security Administration chief Kip Hawley told MSNBC there is good reason Americans fume at the agency, as they did this week following reports that officers patted down a 4-year-old who hugged her grandmother at secure for hugging her grandmother. Hawley, whose book on the agency came out Tuesday, called the agency "broken" and slammed its focus on a byzantine system of regulations at the expense of flexibility and effective risk management. "But in the 10 years since, al-Qaida has proved to be an adaptive enemy. They simply take the defenses that they see and work around them to try something else. The problem at TSA is that each brick that’s been put up has been put up in a wall and stays there even after the vulnerabilities they address have been closed," he said.
