The blog basically says: if you can&#x27;t say be 100% sure whether someone is a terrorist then don&#x27;t bother since it could violate expectations of justice. I disagree since proper machine learning systems would probably distinguish between someone doing something with a red flag only occasionally and a fanatic who does something based on a strong belief. If someone wanted to check me because their system found something suspicious, I would be happy to help because I would understand it is part of national security work. Customs control today makes random sample checks of the passengers and that&#x27;s ok. Just watch Border Security, Australia :) <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=LEiMHdISTvE" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=LEiMHdISTvE</a>
