The whole proposition here is ridiculous. &quot;we must assume any adversary can open any TSA &quot;lock&quot;&quot;<p>No shit.<p>We&#x27;re not talking about a bank vault here -- it&#x27;s luggage. Does anyone, anywhere, have any expectation whatsoever that a luggage lock provides meaningful security? I think I opened my mom&#x27;s luggage lock with my sister&#x27;s hairpin when I was 6 years old, and I have zero lock picking skills.
