In theory, all they&amp;#x27;re supposed to do is a basic administrative search to prevent weapons or explosives from being brought onto a plane. In practice, the perception in the public mind that they are a more general law-enforcement body allows them to easily perform other tasks on behalf of agencies that don&amp;#x27;t have the same general search powers.&lt;p&gt;The classic example is searching for large sums of cash. Detecting large quantities of traveling cash and ensuring it&amp;#x27;s been properly declared is CBP&amp;#x27;s (Customs and Border Protection) job, not TSA&amp;#x27;s. But because TSA gets to X-ray and search every bag and body-scan every passenger, they catch that stuff, and then hold the passenger and go get CBP.&lt;p&gt;The result is that the number of outside-the-mandate things that can end up happening as an &amp;quot;incidental&amp;quot; result of TSA&amp;#x27;s screening is staggering.</text><parent_chain><item><author>idlewords</author><text>I wish there was a transcript to go with these slides, or some context.

I opt out at every checkpoint, and each time, they maximize body contact and then generate an input to those machines. Wouldn&amp;#x27;t it go off for anyone who had smoked up earlier in the day, or the preceding day? It seems like they&amp;#x27;d be spending all their time doing drug searches.&lt;p&gt;(Don&amp;#x27;t get me wrong: drug searches at TSA checkpoints are extremely alarming, because TSA has been given a near all-access pass to mechanically searching people).&lt;p&gt;Fun fact: if you do any welding before you get on a flight, there&amp;#x27;s a good chance you&amp;#x27;ll set those things off.</text><parent_chain><item><author>idlewords</author><text>I wish there was a transcript to go with these slides, or some context.
