Poll: Did TSA Overreact at Newark Airport?

An entire terminal at Newark Liberty International Airport was locked down for three hours Sunday after a woman reportedly walked away prematurely from a security checkpoint. 

The lock-down caused the cancelation of more than 100 flights and the delay of more than 65, reports the Star-Ledger. 

Authorities did not even find out who the woman was until she landed in Cleveland two hours later, the report says. 

This incident is being described as the most serious screening incident to occur at the airport since January 2010 when a college student caused a major scare and airport shut-down after sneaking underneath a security rope to kiss his departing girlfriend. 

Are we being too cautious with airport security?

Should thousands of travelers' lives be interrupted because one woman walks away from a TSA agent? 

Is allowing her to then board a flight and land two hours later at her destination still unfound a demonstration of incompetence? 

Should we be worried?
