TSA: Texas bill banning pat-downs is unconstitutional

The TSA defended the pat-downs, pointing out that about 3 percent of travelers receive them. 

"We wish we lived in a world where you could just walk on a plane with no security screening, but that just isn't the case unfortunately," the TSA blog said. "Aviation security agencies worldwide have been using pat-downs long before TSA was created to prevent dangerous items from getting onto airplanes. The pat-down is a highly effective tool to resolve certain alarms and keep these dangerous items off of planes that could cause catastrophic damage. 

"It's important to note that if a passenger (or bag) alarms during screening, our officers must resolve the alarm before allowing the passenger and their baggage on the airplane," the agency added.
