I think B6 employees has been making mistakes when she gotten through exiting from sterile area without she need to be screened at checkpoint. She won't happening again when she need go back to front of checkpoint. Its not her fault when they didn't realized know her. She was supposed to go through security screening. If someone who went through by exiting of checkpoint. TSA will be result to be fired or suspension from their jobs. It's extremely important where the employees need to being screening front of security checkpoint instead exit of sterile area.
