Several countries now use these scanners. The particular issue (and change) here is about whether people have the right to opt out of passing through them and be screened by an alternative method. In the U.S., that was the case until just now.<p>According to European law, it should also the case throughout the European Union.<p><a href="http:&#x2F;&#x2F;eur-lex.europa.eu&#x2F;legal-content&#x2F;EN&#x2F;ALL&#x2F;?uri=CELEX:32011R1147" rel="nofollow">http:&#x2F;&#x2F;eur-lex.europa.eu&#x2F;legal-content&#x2F;EN&#x2F;ALL&#x2F;?uri=CELEX:320...</a><p>Policies in the U.K. were also changed last year to allow passengers to opt out, which wasn&#x27;t permitted before.<p>The descriptions of passenger screening on the TSA website haven&#x27;t changed to reflect policy change. Maybe they expect it to be used extremely rarely?<p>I&#x27;d like to write to my Congressional representatives about this, although it&#x27;s a bit difficult for me to imagine that Sen. Feinstein will be on my side of the issue.
