<p>HGFM: Indeed (once you have reached legal majority, of course). Of course, your example is spurious because “your room” is normally actually your parents’ property. But yes, if you were 18 your parents would have no legal right to do anything (search, use, etc.) your property - but while that is legally true in practical terms it is irrelevant since they’re normally supporting you and the threat of withdrawal of that support is generally sufficient.</p>
<p>As for your “but if this happened, wouldn’t you be happy to have your liberties infringed upon?”, the answer is a definitive no. I already think the US and many other countries have gone much too far in violating basic human rights and liberties since 9/11, and it is dismaying, though not at all shocking, to see that as time goes on this cavalier attitude towards civil liberties is beginning to be reflected in ever more pervasive ways throughout society. When I see whole crowds of people hardly batting an eyelash at random drug searches or testing in schools, at breathalyzers at proms, or at random and illegal wiretapping, these things truly sadden me.</p>
