Safe? SO, if the TSA officer doesn't like your answer he/she can at their sole discretion decide that you need to be ejected, detained, incarcerated, GITTMOED?
Why not legislating 'travel authorization permits' for DHS approval, before you can leave your house, city, state?
"Oh your leaving for vacation, let's see I have your home address right here" I'll call my buddies and we'll 'secure' all your home's belongings while you're way.
FEEL SAFER NOW?
