HOUSTON --Those controversial full body scanners are now in place at both Houston airports. The new scanners were installed at Hobby Airport this week. Use of the scanners and new screening measures by the Transportation Security Administration have raised serious privacy concerns over the past few months. But that hasn't stopped the government from ordering more of these full body scanners for airports across the country. TSA officials say it is a better alternative than a pat-down. "You're going to beep if you have a titanium knee and you're going to have to be patted down. Now you have a choice. We're finding the public is just thrilled about that," said Rob Parrish, Federal Security Director, TSA. Just this week, New York Sen. Chuck Schumer introduced a bill that would make it illegal to record or distribute images taken by these full body scanners. The TSA says they images are never stored and are deleted after use.
